Email not working: "Too many pending emails in mail queue"

[Octopus]

Hardware: Bought VPS
YUNOhost version: 11.2.5 (stable)
I have access via web admin and SSH

Hi everyone,

I’m currently having problems with email not being sent or received.
When I run diagnosis from the web admin I get a “Too many pending emails in mail queue” warning under email and when trying to email myself in Thunderbird I get “Temporary lookup failure”. This is the only potential clue I have as to why email has stopped working.

Also, I don’t know if it’s relevant or not but I recently changed the main domain. This produced a reverse DNS warning in diagnosis which has since been corrected via my VPS DNS settings.

I’ve found an older post on this subject but the links to help no longer work.

Everything else on my server appears to be working fine.

Thanks for any help you can offer

I nearly ignored this question, just because the default template was ignored, BUT You’re lucky, I’ve seen the 2 last lines before closing.

But maybe other will just ignore it (basically, if people do not even take the necessary energy to fill the template, why waste energy to help them ?).

So, back to your problem.

Can you share the logs of the services that can be involved ?
Like dovecot, postfix, rspamd, or any service that you juge usefull.
