<![CDATA[Suggestion: Clarify Email Client Configuration UI (Port 465 labelling/ inclusion)]]>Just a small suggestion to improve the "Configuring Email Clients" dialog that appears when selecting Configure Email Clients from the mail UI.

At the moment, it lists:

Outgoing Mail (SMTP)
Server: my.domain.coop
Port: 587 (STARTTLS) or 465 (TLS)

This is potentially misleading. Port 465 uses implicit SSL, not STARTTLS — and many email clients (like Calibre, Thunderbird, etc.) distinguish between:

  • STARTTLS (587 – modern standard)
  • SSL/TLS (465 – legacy support)

Labeling 465 as “TLS” can lead users to select “TLS” in their client with port 465, which silently fails or throws confusing authentication errors. This catches me out nearly every time I have to configure something!

e.g. Calibre desktop app has this:

4b2698f5-5b06-4cf0-8aea-c968ba525e1c-image.png

I was using port 465 and TLS as that is literally what the Configure Email Clients from the mail UI told me to do! But that doesn't work.

Suggested wording:

Port: 587 (STARTTLS – recommended)
      465 (SSL – legacy support; may not work in all apps)

Or even:

Port: 587 (STARTTLS – modern standard)
      465 (Implicit SSL – older method)

Or even just:

Port: 587 (STARTTLS)

This would better align with Cloudron’s own docs, which only recommend port 587 anyway.

Thanks!

Have you considered adding the option to let people download mobilconfig files for automatic setup? It's a simple XML file I believe which could be auto generated. There is also this tool: https://mobileconfig.vercel.app/

That sounds good for some use cases. Don't think it would've helped in my "configure Calibre" use case though 🤷

Basically I tell people to simply try out variations of the possibilities until it works. Have you considered adding the option to let people download mobilconfig files for automatic setup?

I just know that speaking personally at least a couple of times (in Calibre and definitely somewhere else too, but I can't remember where now) what has worked is choosing 587 + TLS (which I guess is just being mislabelled etc). But agreed, overall it sucks but not a huge amount you can do about it. Seems it basically an issue of trial and error which is rubbish.

I guess perhaps at least perhaps a small note could be added to the pop-up about how many apps/ platforms have confusing UIs and sometimes trial and error is required (possibly with a link to this thread? 🤷 )

The issue is that some apps/clients label it as "TLS" or "SSL" .

  • SSL itself is deprecated, so it's hard to know what exactly the calibre UI needs. It's also common to refer to TLS as SSL because of history.

  • Let's say Cloudron says STARTTLS is recommended. What makes one choose TLS on Calibre? Only because "TLS" seems like some vague match? But technically speaking, these are two different things. As see in other cases like thunderbird and k9....

Overall, it sucks 🙂

The gnome mail clients use:

Thunderbird also does so

Same K9 and the random email app I have on my Android phone.

Can't say much about how the situation on mac or windows is though, as I don't have such environments.

Best to leave it as-is

But don't say 465 (TLS).

This:

Port: 587 (STARTTLS) or 465 (TLS)

Which is says when you click here:

Screenshot from 2025-07-21 14-19-07.png

Is confusing/ wrong, as it seems in actually existing UIs they never actually go together and TLS tends to actually mean STARTTLS which goes with 587.

I think perhaps something like:

Port: 587 (STARTTLS – often just called TLS. Recommended) or 465 (SSL – older method)

?

That port is now deprecated. In fact, it's been reassigned to something else. See also https://www.mailgun.com/blog/email/which-smtp-port-understanding-ports-25-465-587/#chapter-3

edit: but atleast per https://www.iana.org/assignments/service-names-port-numbers/service-names-port-numbers.txt it's not marked deprecated

Working on it.

I think this is a good suggestion.
These strings are handled by the @translator group/people via https://translate.cloudron.io/projects/cloudron/
If you'd like, we could add you to that group and give you access so you can submit these changes.

But since you stated in the past:

@jdaviescoates said in 33 GB of usage, 177 GB system space occupied - how to find ghost files?:

I'm a bit over stretched at the mo so if you could do it that'd be great, thanks

I can make this change for you.
