I'm trying to connect the mail client built into the Vivaldi browser to my cloudron inbox but when I try to add the account I get this message:
(Note: In these examples, I'm changing my real domain for
example.com; not that you couldn't guess it.) I'm using the configuration listed in my cloudron at: https://my.example.com/#/email/example.com :
Connection details for other email clients
Incoming Mail (IMAP)
Port: 993 (TLS)
Outgoing Mail (SMTP)
Port: 587 (STARTTLS)
Use firstname.lastname@example.org and the mailbox owner password to access mailboxes of this domain
The mail status page shows everything is green.

@infogulch does any other email client work? Thunderbird?

@robi Good question, it seems thunderbird complains about the same thing, but allows you to override it:
After poking around for a bit it looks like the imap server is using an expired certificate. From thunderbird:
But the web server at
my.example.comis using a cert with a valid time range:
Maybe the imap server didn't get restarted when the cert renewed?
There is a bug where the mail server does not get updated with the latest certificate at times. If you go to Services -> Mail -> Restart, it should work after that.
@girish this bug is there already for months and I face it all that time. When will it be solved?
@imc67 just re-tested the mail server restart with the latest code and it seems to happen correctly. so, hopefully, it's gotten fixed with the async/await refactor.
I have also added Service events in the event log for the next release. So, this way, we can know if the service was automatically restarted after cert update.
