Hey Tina,
 
Do you get anything back if you telnet to port 110 of the server (telnet srvemail1.calpont.com 110) ?  Pinging it only means you have a network path to the host and the IP stack is up and running on that host.  I don't know if this is your primary mail server or not but you should also make sure there's actually a process listening for POP3 requests on the server too.  Telnetting to port 110 will tell you that.  I would do it from your OTRS server as well as another host somewhere else on your network.  You'd be surprised how much might have changed in an environment/network where "nothing has changed".  ;-)  If you want to play, you can even log in and check messages (provided your mail server allows telnet sessions, some have a setting to disable manual interactive telnet sessions), type:
user <USERNAME>
pass <PASSWORD>
 
You should get back +OK responses with the one after entering your password telling you how many messages are waiting for you.  You can even view them by typing:
retr <#>
 
Delete messages:
dele <#>
 
Where # is a message number 1, 2, 3, 4, etc. 
 
Close connection:
quit or the standard <CTRL> ] to disconnect a telnet session works too.
 
This is basically all any POP3 client does, OTRS included I'd imagine.  I'm no programmer but that section of PostMasterPOP3.pl (around line 125) is dealing with not only host name but also user credentials so make sure your user name is still valid and/or not disabled on your mail server too.  Telnetting to the mail server and actually typing the commands should help shed light on that as well.

Subject: [otrs] ERROR: OTRS-PM3-10 Perl - Message: Can't connect to <mailserver>

For some odd reason, my mailer is not working properly.  Nothing has changed but when I try to test the PostMasterPOP3.pl manually, I get the following message, although I am able to ping the mail server.

HELP!

 

[root@srvotrs bin]# ./PostMasterPOP3.pl
