Hello,
I run a qmail-ldap server and reccently had a huge amounts of email
queued up due to a specific situation. I use qmail-ldap as a message store
as well as a relay for other customers who have their own mail servers.
Here is the situation: Customer X has a cron job that emails an account on
Customer Y's iPlanet Messenger Server. Both customers use my qmail-ldap
server as a smart relay host. The cron job sent an email that contained a line
that was greater than (1024) bytes. Custmomer Y's mail server rejected it with
the error:
Remote host said: 550 DATA line too long Max(1024)
The bounce went back to "mailer-daemon" at Customer X, who also rejected it
with the same error. The cron job was continually sending emails. As you can
see the bounces were piling up. In just a couple of hours, I had over 80000+
messages in the queue. I got Customer X to fix up the script and cleaned out
the queue on my relay.
Should not qmail detect this loop and discard the email ?? Is there something
I did not setup properly ?? Is this the way qmail should work ?? Is there a
way
I can force all mail sent "TO:MAILER-DAEMON@ANYWHERE" to /dev/null or even
better have a file of email addresses that get quitely sent to /dev/null.
Thanks,
/RS
