 AI> I don't use pfsense so I don't know if this applies to your situation..

 AI> sudo /sbin/setcap 'cap_net_bind_service=+ep' bbbsd

 AI> The above command will need to be run whenever your application is updated

Ack, partially user error.  I never set up a software firewall rule for my
email server...  Now that that's done, port 940 and port 110 are open on my
domain.  Port 119 was just weird.  I removed and re-added the rule and then
it suddenly started working.  Everything is groovy now.  Thanks for all of
the suggestions!
