Sujet: [Exim] mail log parsing
Hi All,

I don't know if this will help at all, but I've knocked together a quick and
dirty perl script that parses exim's mainlog file and outputs it on one
line.

It takes optionally two arguments, the first is the name/mailbox to search
for.
The second is the path to exim mainlog. defaults to
/var/spool/exim/log/main.log
