Error Connect to Bounce

[james1]

Hi,
When I test my mail settings here is the error message I get.  I am able to send/receive mail using outlook no problem.  Any info on how to rectify the problem would be much appreciated!

Bounce Handling]

can't connect to mail.peppersparties.com The bounced message mailbox is not configured correctly.

SMTP is working fine.

Thanks for your help.

When I try a manual telnet to the hostname and port I am able to make a connection:

# telnet mail.example.com 110
Trying 12.34.56.78...
Connected to mail.example.com.
Escape character is '^]'.
+OK <12327.1213453173@pop16.prod.mesa1.example.com>
^]

Therefore I would assume there is either a DNS problem on the server, or this connection is limited by a software firewall.  You could ask your host whether or not there is a limitation on connecting to POP email accounts using a PHP script running on your site.
