Cloudron Forum

@artd2019 Currently Cloudron does not offer (a documented) "whitelist" / "allow list" function, so there is no way to guarantee deliverability of an incoming email. There is a feature request for it already that I'd encourage you to upvote. Version 6.3 coming in the not too distant future is supposed to deliver on many of the email improvements users have been clamouring for (including myself). One thing you can do if you're not already is making sure to remove those emails from the Junk / Spam folder in order for SpamAssassin to unlearn the message as spam. Eventually after a sufficient number of them, it'll learn that those emails are not spam and will decrease the BAYES probability of it being spam. On a related topic, you may want to consider enhancing your SpamAssassin rules list from the defaults, specifically in your case the BAYES_## rules perhaps as I have offered previously in this forum.

@girish Cool, thank you kindly. It's just for incoming mail to those addresses for the time being, but I may add auto-responders from them as well at some point. For interest, I'm setting up all sorts of automations in EspoCRM, so tasks@domain.com will create a Task record and auto-reply to confirm it's been created. Doing similar for other data objects to.

What I would like to do is that if I try to login to a new WP installation with the cloudron super-administrator user, an administrator user will be automatically generated in WP with my Cloudron access data. And if I enter as a common Cloudron user in WP, a user will be generated with their Cloudron access data with the role that I configure in the ldap plugin. In this way, if I also changed my login details in Cloudron, it would also change on all WP sites. This would also be good with the rest of the applications. It would simplify things a lot. This is possible?

@girish I think that would be a good change. I also think I should have gone through the Troubleshooting document sooner : https://docs.cloudron.io/troubleshooting/ Thanks!

@subtlecourage said in Outbound SMTP not working on my External Relay: It says it should be coming from noreplay@domain.com, but instead it is coming from imanalias@domain.com Can you clarify what you mean by "it says"? Is there some error/warning somewhere? Also, I assume that you have put a custom domain in fastmail and also fastmail is able to relay mail as any email address i.e <anything>@domain.com ?

@d19dotca Sadly, they do match. I'm guessing it's something with my current setup that's acting funny. I'll ignore it for now since I plan on migrating either to the new Contabo server that I got or upgrading my current one at DO to Ubuntu 20.04. I just thought it was a wrong setting on my part. Thank you for looking into this and for sharing the custom spam rules! I know you've put a lot of time into that [image: 1620396102638-2443c4d7-ec13-4149-add3-28e1e7ad48ed-image.png]

@d19dotca Perhaps even a per-app option, as in "Check for spam sent from this app."

@girish said in Email into apps - DNS/MX/CNAME/TXT: You have to setup the CNAME/TXT for the root domain and not for my.example.com. You don't have to set it up for each app individually Thank you. That was my main issue.

@girish what about just a normal organization level rights separation? I mean - it's really two different set of roles: 1st line support, dealing with mailboxes 2nd or 3rd, making sure the system and services are up and running. I don't need hiding anything, I just want to ensure my users can manage they mailboxes and users for they own. For now I have to temporary give admin permissions to the 1st line and that's kind of risky...

Per https://github.com/Monogramm/autodiscover-email-settings/blob/66c144e923f245dc0b4e64421449afedcad64052/index.js#L89 this is served at /email.mobileconfig?email=username@domain.com . I am yet to find an official doc page that says this though. However, ChatGPT thinks it is configs/email.mobileconfig served with content-type set to application/x-apple-aspen-config ...

There is a "Spam" filter type in next release - 6.4

@d19dotca since we had some recent timeout issue with the services view (and mail being a service here) it could be that also here the mail container or the server overall is busy during that time and thus the search queries timeout. If you see this happening again, a look into the system/box logs as well as mail service logs should reveal this then.

DNSBLs are configurable in 6.4

I just realized part of this is a duplicate of one that @marcusquinn filed earlier for Add a setting for sendmail limits per mailbox per day

For reference, Haraka has a greylisting function built in: http://haraka.github.io/plugins/greylist/ - and it works with the DNSWL / whitelist which we should enable too. That way if an IP is on the DNSWL, it automatically skips any greylisting attributes.

@girish said in Change to the DKIM record hostname in recent version, caused by new feature or from using NO-IP domain provider?: If it was random, I was afraid there is still a possibility that they can conflict across servers Great point - that makes sense. Thanks Girish. Side note: I think it'd still be great for the OCD in some of us to be able to regenerate the DKIM record on demand so it not only follows the new hostname pattern in Cloudron but also generates a new key if desired too.

@nebulon thank you! worked perfectly fine and is very helpful

@mdreira said in Lightmeter - Mail server delivery monitoring: What mail server does Cloudron use? Exim? This is what Cloudron uses for smpt: https://haraka.github.io/

@nebulon Will do, thanks!

You can set flags on the email with sieve filters. I think this is only available in roundcube UI though. [image: 1613671026536-bf4f52b4-5648-41a9-aca2-f799daadb640-image.png] Then, in thunderbird, you can highlight them accordingly - https://support.mozilla.org/en-US/kb/message-tags
