I'm having trouble getting the "process bounces" feature to work.  Here are the two setting options in config.php and the error messages received for each.

1. $bounce_mailbox_port = "110/pop3/notls";

Cannot create POP3 connection to mydomain.com: Can not authenticate to POP3 server: Authentication failed.

2. $bounce_mailbox_port = "110/pop3"

Cannot create POP3 connection to mydomain.com: Certificate failure for mydomain.com: Server name does not match certificate: /C=US/2.5.4.17=92807/ST=California/L=Anaheim/2.5.4.9=1360 N Hancock St./O=Add2Net Inc./OU=Lunarpages Division/OU=Hosted by Add2Net, Inc./OU=Comodo PremiumSSL Wildcard/CN=*.lunarpages.com

I'm not sure which of the above is closer to being right and what needs to be done to correct it.  I've followed the tutorial at http://forums.phplist.com/viewtopic.php?p=45136#45136 but this seems to be more of a server problem.

Any assistance is appreciated.
