Email Queue

[Matt Smith]

Is is acceptable to have 250+ emails in the queue at all times? I am worried that it might be affecting my VPS. Any help would be appciated.

[Frank Broughton]

No it is not in my opinion. Force a Queue run in WHM...

[Matt Smith]

Forcing these emails has no effect. 95% of the emails are bounce backs from spam.

i.e.

Spammer sends spam to unknown_recipient@domain.com, the server rejects the message and tries to send a NDR to the spammer, their address either doesn't exist or the server won't accept the mail, hence the reason it is stuck in my queue until it expires!

If you are using exim, here is the solution:

edit exim.conf and set these settings:

deliver_queue_load_max = 2
auto_thaw = 2d
ignore_bounce_errors_after = 12h
timeout_frozen_after = 1d

then run "crontab -e" as root and add this:

0 0 * * * /usr/sbin/exiqgrep -i -o 259200 | xargs /usr/sbin/exim -Mrm >/dev/null 2>/dev/null

ya - what he said or just delete them manually with this addin to WHM: http://www.configserver.com/cp/cmq.html

Will give that a try mate, I had already set the bounce errors to 3d from 7d but will try your method. What exactly does the deliver_queue_load_max line do?

Thanks for the info!

it won't process the queue if the cpu load average is over "2".

basically, it won't add extra load on an overloaded server, very useful if you are being hammered with HTTP requests or spam and SpamAssassin is overloaded.

The better approach is to set the default address for the domain to :fail:. You can do this from the cPanel > Mail section. For more information regarding default address, please check the below mentioned KB:
