I hate to sound repetitive with postings (as there are quite a few of these similiar topics already).
The Problem: It seems each time CPanel updates or the server restarts, "exim on another port" under the "service manager" option in CPanel, fails to work.
The Ghetto Solution: Change the port to another port and change back to the original port number or possibly uncheck the option for another port and check back. This must be done EVERY TIME the server reboots or CPanel is upgraded (as the folks at Cpanel with all of their infinite wisdom has yet to resolve this).
A newly Discovered Solution: Track down /etc/chkserv.d/exim-26 (replace 26 with whatever port number your alternate port is set to) and remove all the spaces before the line of command (as mentioned here: http://forums.cpanel.net/showthread.php?s=&threadid=9170)
The NEW Problem: Now, no matter what happens, the alternate port setting no longer works. Could it be a problem with chkserv? Perhaps a new CPanel build? No telling. Anyone have any ideas?
