Question e-mail queue

[abaum]

Hello,

In the e-mail queue from time to time harmless e-mails of users hang. The documentation does not go into the real reasons. It is recommended to remove the emails from the queue or delete them. What is the difference between removing and deleting? How do I get the affected emails to the recipient or sender?

Greetings Andreas

I suppose you could remove the message from the queue and save it or you could delete the message altogether. That's the only difference.

Depending on your server's configuration, once the outgoing message has been in the queue for too long, the sender will get a notice and the message will get removed from the queue.

As to what might be the cause for messages not getting delivered, there are many possibilities. It's impossible to know without inspecting the logs and seeing the error reported by the recipient's server.

Some of the possible causes: graylisting, IP blacklisting, sender blacklisting, DNS errors, etc..

It might be anything. You might have 5 messages lingering in your queue and all 5 could be stuck because of a different reason. This kind of issues happen daily on mail servers.
