    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 <quotes@>
    1 <wra@>
    1 <stirling@>
    1 <sales@>

    I see 1651 message that seem to have no senders.

    This is one of the headers:
    Code:
    mailnull 47 12
    <>
    1480597551 0
    -ident mailnull
    -received_protocol local

    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
