Have been working wtih tech support and definitely some email sin teh queue seem like the server is trying to send something out. Still not sure what this is yet. But I did notice that many of these emails were form the tell a friend script. Any ideas why these are stuck in here? The tell a friend script is written in PHP.
But even if the email address was bad, it should still send out right?
1. Log into WHM
2. Navigate to Email -> Mail Queue Manager -> View your mail queue, click on deliver now beside one of the messages. It will either deliver or spit out an error. If you give us the error, we can probably tell you what's wrong.
As for the firewall, if you're running apf do a service apf stop via shell, then execute an iptables --flush, and try to deliver a mail again. If that fails, restart apf and give us the error.
If you're running csf, navigate to the CSF management at the bottom of WHM's left-hand bar and turn the firewall off. Repeat the mail sending test. If you still can't send it, give us the error.
