Which qmail log file details outgoing mail? (have huge outgoing mail volume)
I have an SME7.4 server with qmail.
I got an alert from the server that 133, 433 and 78 mails had gone out in 3 consecutive 5 minute periods.
Have looked at various log files but can't seem to find one that shows outgoing mails.
That amount of outgoing could happen if our server was receiving a heap of spam and throwing back failure messages (I think), but there was no notification of lots of mails in (which does happen at times).
Really don't know how to figure out what has happened but would like to know.
Any detective clues would be much appreciated.
