    We have an SMTP app which sends out customer invoices. Occasionally, this loses connection the the mailserver.

    Today, I found these in the traffic monitor of our internal firewall and wonder if it's connected.

    Connection Refused 15 ???

    At this stage I've no idea if the internal firewall refused the connection or CSF did or even the mailserver ??

    Any ideas ??

    Hello :)

    You can search /var/log/exim_mainlog for those timestamps to see if Exim reports any activity at those times:

    Code:
    exigrep DATE/TIME /var/log/exim_mainlog
    Thank you.
