I keep getting this error in Mail Queue for several domains I am hosting myself on Cpanel servers:
host lookup did not complete
So, a user on one of my servers sends mail to user on one of my other servers.
Also some domains outside my server are rejected, but I think that's false to for some of them.
It seems to randomly choose some domains for which it is not able to lookup host.
What could be the problem?
