Why are my emails taking forever to send on my new linux-based plesk server?
Simple! Due to the nature of the anti-spam facilities built into Plesk, one nasty side effect is that email sending can be delayed. Below is the solution!
Open up /etc/inetd.conf in your favourite text editor. Move the cursor down to where it has smtp and smtps.
Now you're going to carefully edit the following lines with these changes:
Locate tcp-env /var/qmail/bin/relaylock in the middle of both the smtp and smtps lines and add -Rt0
in between so it looks like tcp-env -Rt0 /var/qmail/bin/relaylock
There we go! All done!
