Connection to the POP3 server is timing out

I would like to now more about a warning about our POP3 server.

We have a message in our Discourse admin dashboard :

Some advice based on your current site settings

Connection to the POP3 server is timing out. Incoming email could not be retrieved. Please check your POP3 settings and service provider.

=> In the [Mail Settings] we have a maijet api setted-up that seem to work correctly. We can see logs of mails in the [Sent] or [Received] that have been sent or received recently.

I don’t understand why this message shows up and how to fix it. I don’t see any config option to use something else than POP3 to receive or send mail. And the current configuration seem to work as expected.

Can you help me understand what’s the problem is if there is any?

Thanks

POP3 is about receiving, so we can ignore all the sending bits.

How are you receiving emails? The choices are:

If you have both configured, then maybe the POP3 settings are obsolete. You could try if simply disabling pop3 polling enabled does the trick.

Also, you can check /logs on your server for any clues.

How many mails are waiting to be processed? I once had “delete messages from server” disabled. After some time I got connection problems.
