Just today I started getting a load of mails sent to the postmaster@mydomain.com with the following info in the email:

I though that it would be a storage issue so I checked:

Any ideas? I went and deleted a bunch of emails, but now it will not even let me connect to my mailbox to delete more out....

Please help!!

I have been doing some work on cleaning up whatever I can.

This is what I have it down to so far.

Turns out someone sent a 300MB+ video to a user and it was blocked by amavis, but the virusemails and quarantine folders are within the /var/spool folder. With that large file in the spool folder it stopped the spool saying the 'Insufficient system storage'.

Does anyone know a way that when amavis blocks those type of files (by file type, say .mp3, .mov, .mpeg4, .wmv, .exe, etc....) that it rejects the email and sends a responce stating that?
