My mail queue is filled with these. I thought that it was a spammer who attacked one of my clients and that exim was trying to send back to the spammer.... but now I'm starting to wonder. Your thoughts:

All accounts on the server are set to :fail:

Are you thinking that exim is trying to send a reply back to the spammer with "Mailbox is full"... If so, is there a way to stop exim from doing that?

Thanks!

This things happens when spam comes to a full mailbox and the bounce goes to nowhere. So it get stuck in queue.

You may decrease this values on /etc/exim.conf for earlier delivery and flushing. I would recomend that you comment the auto_thaw line.

It may look like this:

#auto_thaw = 7d
ignore_bounce_errors_after = 30m -> you can adjust this settings at your choice
timeout_frozen_after = 1d -> you can adjust this settings at your choice

ignore_bounce_errors_after will retry a bounce message delivery and fail if not delivered.

timeout_frozen_after is if a frozen message of any description that has been on the
queue for longer than the given time will be automatically cancelled at the next queue run

Bye!
