lots of emails in bounce queue

[asmithjr]

I am not sure how to handle this but each day I see tons of emails with the subject
Mail delivery failed: returning message to sender when I check the ConfigServer Mail Queues, not to mention lots of others that stay in queue for days. I can filter using Bounce Emails to just delete these emails but that would keep me busy in itself.

Most of these seem to be from aol.com and yahoo.com and are addressed to users with a to address of aol.com and yahoo.com

I guess I am confused how the emails are even on my server to begin with. The only thing I can get back to is the use of "fail" but everything I read is that is the proper setting to use.

Do you mind shedding some light on this for me?

Hello

Review the message headers for some of these messages to see if you can get a better idea of the source of the message. Is it possible they are bounces from other servers due to SPAM sent out by a user on your server? Have you tried searching the email addresses in /var/log/exim_mainlog to see if you can find any more details?

Thank you.

i found the domain and reset the users password. I know they cannot receive email now until the find out the new password but this has stopped all the emails. Looks like his problem is with the computer he is sending from.

Thanks
