Well, I gave myself a fun little short project (took maybe 30 minutes) today where I replaced every app icon in the Dashboard of Cloudron. Here's what it looks like:

I used FlatIcon's website, filtering to Free icons and for Linear Colour as the style. I was surprised at how many fairly accurate icons I could find, even one for my email 'autoconfig' app which I had doubted I'd be able to find a good icon replacement for. Even found separate ones for the two websites which aren't really websites at all but just redirect visitors to another externally hosted website on a different domain (two clients are realtors who just wanted their own short marketing domain name for email and then having the web address forward to their actual realtor's webpage for their own listings), so they're literally just the LAMP app with a single html file which does an immediate redirect.

I may make further changes, or heck I may even revert back to the default app icons in the future, but I thought this was a nice little distraction to change the overall look of the Dashboard by replacing all the app icons with new ones, and ensuring a bit of consistency where possible between them all too so that none of them stood out from others. I think it went fairly well. Just wanted to share to maybe inspire others if they think they'd benefit from some extra bit of flair in their Dashboard.

As Radicale isn't the most RFC-compliant (they even state that's not their goal), it'd be nice to have a more compliant CardDAV and CalDAV server to use as an alternative to Radicale, SOGo, and Nextcloud.

A good one I have seen recommended often is "sabre/dav". It's also updated more often than Radicale too from what I can tell. I think this would be a great addition for those people who want a more pure CalDAV and CardDAV server.

@jdaviescoates Great idea! I'd definitely love to be a part of something like that.

What I do:
I do freelance web & tech services as a side business, and that includes hosting a bunch of things for customers which I do on Cloudron. Specifically WordPress websites for roughly 15 clients, and recently even some SFTP servers for one client too. Also a nodeBB forum for a client, Bitwarden password manager, email hosting of course, webmail apps, all that jazz. WordPress and email is the vast majority of what I host for my clients, but I get to dabble in other areas too which I like. Oh and web analytics too of course as that's bundled with my web hosting plan I sell to them, and to my surprise many of them actually really like seeing the emailed report from Matomo where they see all the results from each city, country, dates and times of busy traffic, etc. When I started offering it I honestly didn't think too many people would care, but most of them really like that part. I guess it sort of helps justify to them why they have a website in the first place so they can see how many people they're effectively reaching and such too in one area.

I don't necessarily market my services as a Saas-Cloudron or anything like that, just to be clear in case that's kind of what you were asking earlier, but I am very open in spreading the word of Cloudron (sounds like I'm in a cult, lol) to any of my clients that want to learn more about how I manage things, and even link to Cloudron from my website, so generally the customers that actually care to know that stuff all know I'm using Cloudron as the platform for everything.

Quick side story about the SFTP server I recently setup, just because I think it's really cool, haha:
Using Surfer, I setup an SFTP server to bridge a medical clinic (client of mine) administering COVID-19 tests and the lab they hired to actually process the tests. Before, they were emailing constantly between clinic and lab and it was a hassle for them to keep track of everything... and we later found out that the lab they contracted actually had a script which they use for their larger clients I guess - it polls the SFTP server every 5 minutes for a CSV file which the clinic fills it out and saves to the SFTP server for each patient, each patient being it's own row on the CSV. It's streamlined their entire process now - just that one thing alone - to the point where they get their results much faster now from the lab and can then forward that to the patients much quicker than before as it's way less overhead in communications between the lab and clinic. Once I heard about this and set it up for them and learned how much better it made things for them, honestly I was humbled in a way, I consider myself fortunate to have been a very very very tiny part of that process to ensure people can get their COVID-19 test results sooner. It really wasn't much work on my part at all, Cloudron made it easy to implement! It was still cool to be a part of an improvement to this essential service in my region none-the-less.

Sorry I'm rambling on now, lol, the answer to your original question is "Yes, I offer services to my clients that I host using Cloudron". haha.

These apps serve different purposes, so I don't think one can really answer the question without knowing the use-case.

My suggestion is if you only care about webmail, then Rainloop wins. It's quicker, nicer interface (IMO), intuitive, etc. If you however also want to manage a calendar and contacts, then SOGo is likely the better one as Rainloop does mail and contacts only, no calendar or anything like that. And even for contacts, it's differently managed - Rainloop simply stores them, but SOGo "hosts" them so they're also accessible via CardDAV protocols into apps like Contacts on macOS or iOS, Calendar on macOS, etc.

Basically, Rainloop is a webmail client whereas SOGo is what's called "groupware" as it will sync contacts, calendars, tasks, etc. in addition to the mail client role.

If you elaborate on your use-case, then people can probably give you a more accurate answer. Hopefully the above helps in the meantime.

I've been spending a long time lately on spam improvements on the Cloudron mail server. I've made a ton of improvements and while still not perfect (it never will be) it's a giant leap over how it was a few weeks ago.

I already made some updates in the other post on DNSBLs, for anyone who hasn't seen that already.

I've also improved the spam classifications for anything that gets past the DNSBLs. It was already pretty decent at classifying spam that was spam with no false-positives, however there was still a good amount getting to the inbox for some users in particular. I've trained them to use the spam folder and archive folder accordingly to train the filter for their account, but I also made a whole bunch of tweaks in the custom rules to overwrite scoring server-wide.

Tip: You can easily override the default SpamAssassin scores or even create your own rules using the Custom Spam Filtering Rules feature in Cloudron.

I thought I'd share what I have currently which adds in a few new providers as well as increasing the scores from their defaults. Here is what I've got currently and it seems to be working very well for me and my users with no false-positives that I can find and much more in the spam box where they should be. Feel free to adapt of course for your own servers.

The main highlights of the changes I made was the following:

• Increasing the scores for various DNSBLs where appropriate from their defaults
• Increasing the scores for SPF failures but keeping them still reasonable as not ever mail server has setup SPF correctly even if legitimate
• Modifying the scores for the BAYES_ learning ones, scoring them according to their confidence levels (and a bit above the default in most cases)
• Added three new DNSBLs for SpamAssassin (seen at the bottom of the list) which when combined with the overall scoring changes for DNSBLs built-in has provided a noticeable improvement in spam recognition

@imc67 I definitely agree, lots of areas for improvements.

I do have one item of your post I wanted to share my two cents on though...

Wordfence imho needs to be installed by default in Wordpress

This is just my personal view so take it with a grain of salt of course, I don't think there's really any right or wrong way to it. My two cents...

I have the belief that we should aim to keep all apps (WordPress included) about as close to default as the developer intended for the app, leaving Cloudron to just handle the default user and mail config for the app, etc. I think it's a bit of a slippery slope to add in all these extras regardless of how important they may be for certain use-cases, because the line needs to be drawn somewhere of course and deciding where that line is isn't particularly clear. In such a case, I'd ere on the side of "keep it as close to default as possible as intended by the developer" to stay free of any tightrope walking so-to-speak. haha.

For WordPress in particular, there's practically hundreds of thousands of plugins available, some of which are "default installs" in my environments where I have a template setup with the ones I use all the time for example, but I would never want to force my defaults on others because what works for me or the plugins I prefer to use may not work or be preferred by other users. Security plugins are one area where there's a ton of them, and there was a similar discussion not too long ago I had regarding a suggestion for including a caching plugin by default too.

And that's kind of the slippery slope I am referring too... what is the criteria for when a "default plugin suggestion" gets approved, and when would one get denied?

I just really want to see apps be as close to default as possible. But of course that's just my two cents. I'm sure many might disagree with me. haha.

I totally agree with the rest of your suggestions though, I would love to see the improvements for additional security in the Cloudron server itself. I completely forgot about the GEO-blocking request for countries, that'd be pretty great to have!

I just realized from comments on a different thread that you now have yearly/annual pricing which is a generous discount per month. I may have missed the announcement of those pricing changes, not sure when that came into effect but I appreciate it.

As a Canadian who ends up paying even more than the listed price due to currency conversion between USD and CAD, I am very thankful for the chance to have that discount by paying for a year in advance. Of course one has to have the means to be able to justify a year up-front, but I can definitely see myself using this for a year or more at least.

As a result, I have changed my plan from monthly to yearly, and I just wanted to say thank you. This brings down my total cost of ownership (TCO) by quite a bit. This takes me down from roughly $40 CDN to $20 CDN, saving me $20 a month, or $240 over the course of the year.

Anyways, ultimately I really just wanted to say thank you, and hopefully let others know about this too in case it helps them. This was a pleasant surprise to see.

Reference: https://cloudron.io/pricing.html

Just thought I'd check-in on the status of 6.3.0.

@girish It's also quicker to do from Cloudron at times depending on the VPS host as well. For example I'm hosted currently at OVH and it's not the nicest control panel, not super mobile friendly either and takes me about 6 clicks to get to the reboot option. Cloudron is only about 2 (login > System).

It'd be great to have the ability to add comments to backups, particularly app backups.

My example use-case: I have a WordPress app running, which I am working on some performance-projects. I'm making backups after each different plugin change for example to be able to easily restore back to baseline and after certain plugin changes. After making so many app backups, it can be difficult to later remember which one was the baseline, which one was for any particular plugin change, etc.

Having the ability to add notes to app backups would be a great way to handle that type of use-case.

I picture the UI with a small icon next to each backup to easily add notes. Then to view them, it'd be great to have it either pop-up when hovering over a backup or to perhaps have a short accordion effect to expand the notes applied to the backup. The latter would be more mobile-friendly as mobile devices don't really have the ability to "hover" over items.

@christiaan Those two lines don't tell me too much, unfortunately. But I did notice you are using macOS 12.0 which if I'm remembering right is the latest beta of macOS Monterey which isn't actually out yet for the public outside of the beta channels, so I'm wondering if perhaps this issue could be caused by some bugs in macOS Monterey and it's implementation of it which doesn't work with NextCloud for shared calendars? I'm not certain, and I guess it's unlikely since I had found that very similar issue in GitHub for OwnCloud and they were even using an Android client, but who knows. Do you happen to see this issue if using a more supported macOS version (11.x "Big Sur" and lower?) with the built-in Calendar app?

Funny, I just noticed this as well the other day but I figured it was just me because I'm running macOS beta so thought the new Safari overhaul killed something. haha. Glad to know it's a known issue and already fixed for the next release.

A HTTP 501 means the server didn't understand the function from the request. Reference: https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/501

My guess is the NextCloud implementation of CalDAV doesn't support the CalDAVUpdateShareesQueuableOperation operation as it states in the error you included from the client side.

It may be helpful to get logs from both sides to see what each say about it, because sometimes it's easier to piece together the missing parts or reasons why by comparing the logs from each side of the transaction.

If you're sharing calendars, that may be an issue if NextCloud doesn't support it. Reference on an ownCloud repo issue: https://github.com/owncloud/calendar/issues/828

Figured many of us might find this one quite interesting: https://arstechnica.com/gadgets/2021/06/the-big-alternatives-to-google-photos-showdown/

Just curious... are you sure you're using the Standard login option? I have been caught by that a few times ever since they enabled LDAP login method since the LDAP login method is the first one that comes up on the login page. Just thought I'd mention it since it's caught me before too.

@atridad Yes, this would be awesome. Almost like the current Services page already shows memory usage in a bar for each service. I think that'd be a good way of implenenting that @girish... adding that same Services logic for memory visualizations to the System > Memory tab perhaps underneath the line graph there.

@nebulon It may be a good idea to allow customization of the notification system, so that those users who deem everything uber critical (for business reasons and such) can be notified upon every failure, and those who are more using Cloudron for their hobby can choose to not be bugged by failures as often due to the very real reason that led to this change in the first place... too many false-positives or intermittent issues that no sysadmin can necessarily do anything about anyways (i.e. if the object storage provider is having issues).

If you want to keep it 'simple' still, then maybe just have two options for users... aggressive or non-aggressive. lol.

@chymian-0 Side note not meant to derail the great conversation (as I can certainly see both sides to the equation here)... If your backups are critical (which they are for many of us), it'll be infinitely better to backup multiple times a day, not just once. As a side benefit, you'd be notified sooner if any failures too. Personally I backup about 4 times a day (though I tweak this occasionally).

@mehdi Ah yes, I've been meaning to report this bug too. Good catch, it's quite annoying.

@jdaviescoates Oh yeah great catch! I'm sure that was a copy/paste mix-up as it's stating that in the older 6.3 announcement too. Wouldn't make sense to announce something that's not actually coming. haha
