[nmglug] Comcast mail DNS resolution

[Tom Ashcraft]

Thanks Akkana,

Ping and ftp commands indicate that for some reason at least three 
Comcast mail servers are apparently permanently suffering a "Temporary 
failure in name resolution":   imap.email.comcast.net, imap.comcast.net 
and, two days ago,  mail.comcast.net.

imap.ge.xfinity.net Seems to work fine in lieu (a workaround I stumbled 
upon on the Mozilla support forum), but the appropriate SSL certificate 
either doesn't get served, or, despite considerable tutoring complements 
of various NMGLUG members, I still don't fully understand how I'm 
supposed to acquire it (probably both).

Tom
