Hi Guys,
I recently became the admin for our companies cPanel server, mostly it plods along with no issues and I've not had to do to much but it looks like I need to investigate an issue that keeps coming back and needs a proper solution.
If I run the following cmd on my server I get back the top 5 results of emails sorted by the recipient.
# exim -bpr | egrep '^[[:space:]]{,3}[[:digit:]]' | awk '{print $4;}' | sort | uniq -c | sort -nr | head -5
1651 <>
4 <[email protected]>
1 <[email protected]>
1 <[email protected]>
1 <[email protected]>
I see 1651 message that seem to have no senders.
This is one of the headers:
At this point I am unsure how to proceed, sure I can remove them all as I have in the past but I'd to try and find out whats causing this, how do I go about this?
Thanks
Paul
