I am receiving lots of "Mail delivery failed : returning message to sender" emails which are being sent to "[email protected]". WHM currently forwards mail for root to my own email address. I'd rather not receive this emails so I thought I would set up filtering to stop them coming through to my mailbox.

I set up a Global Email Filter as well as an Email Filter on my email account, neither of which had any effect. The Filter Trace Results section did apparently match the condition though:

Code:
The Filter has matched the following condition(s):

    $header_subject: contains Mail delivery failed : returning message to sender

Return-path copied from sender
Sender      = [email protected]
Recipient   = [email protected]
Testing Exim filter file "/etc/vfilters/server.com"

Headers charset "UTF-8"
Save message to: /dev/null 0660
Filtering set up at least one significant delivery or other action.
No other deliveries will occur.
Then I tried creating an Exim Filter at /usr/local/cpanel/etc/exim/sysfilter/options/

Code:
# Mail delivery failed: returning message to sender
if $header_subject: contains "Mail delivery failed: returning message to sender"
then fail
endif
Code:
# Warning: message 123456789 delayed 72 hours
if $header_subject: contains "Warning: message" and $header_subject: contains "delayed"
then fail
endif
I went to the Exim Configuration Manager, enabled the filter and restarted EXIM but that hasn't worked either because the emails still come through. Can anyone help?

Thanks
