We have a few machines where /var/spool/nullmailer/failed/ regularly gets filled up with bogus mail. The 'To' address for the emails filling up /var/spool/nullmailer/failed/ is '#@<>' (without ''). I feel like this is the result of some kind of failed variable substitution, where '#' is supposed to be the local part and '<>' is supposed to be the domain. Is this a result of sending mail to an empty address perhaps?
Either way, /var/spool/nullmailer/failed/ fills up and the disk runs out of inodes, seemingly because of infinite retries by Nullmailer.
In a mailing list somewhere, I read '#@<>' is a 'special address', without any further explanation of why it'd be a special address. The ##postfix and ##exim folks don't know either.
Has anyone seen the same behaviour?
Nullmailer version: 2.1-7
Scheduled Maintenance: We are aware of an issue with Google, AOL, and Yahoo services as email providers which are blocking new registrations. We are trying to fix the issue and we have several internal and external support tickets in process to resolve the issue. Please see: viewtopic.php?t=158230
Nullmailer creates loop by attempting to send mail to #@<>
