Public service announcement...
Comcast (former AT&T Broadband) is officially switching over the
domain names for their mailservers today. If you know someone at an
email address of the 'attbi.com' domain <*cough*>, it's changing to
'comcast.net'; moreover, said users won't be able to connect and check
their email (and sadly wondering why no one writes...) until they make
some manual configuration adjustments, unless they ran the 'auto-config
wizard', and rebooted this morning.
