Title: tens of thousands of spoof/spam mails hog up mailq :
will 'postsuper -h' placed in a crontab help ?
I have a case where tens of thousands of spam & spoof emails
jammed up my
Linux SMTP mail queue (not that I don't have an anti-spam
policy but many
of these mails are innocently/accidentally blasted over by
internal colleagues):
mailq | grep MAILER | wc -l ==> tens of thousands
A queue full of undeliverable bounces is caused by accepting
mail you can't deliver. Don't do that.
[snip discussion about sending mail to the hold queue]
Question is :
are the 'held' mails still something that will be scanned (& thus
prolonged the scan time) or scanning of mail queue will skip
Postfix ignores mail in the hold queue. Moving the offending
mail to the hold queue will solve your immediate performance
problems.
But going forward, solve the right problem.
