With a simple bash script you can find out a lot.
This is my findmsg script the only parameter you need is the Message-Id
without the <>
#!/bin/bash
SEARCH=`grep -E "$1" /var/log/mail.log | \
awk '{ printf "%s|", $6; }' | \
sed "s/://g" | \
sed "s/NOQUEUE|//g" | \
sed "s/|$//g" | \
sed "s/message-id=<//g" | \
sed "s/resent-message-id=<//g" | \
sed "s/>//g"`
echo $SEARCH
grep -E "$SEARCH" /var/log/mail.log |less
This will give you all log lines for one message. Subject is not included.
And I know this is something that I clobbered together in about 2 mins so
yes it can be optimized.
