As many of you know, AT&T is doing away with its WorldNet service and
switching those users to its Dial Internet service. After making the
appropriate changes to my server settings in SeaMonkey, I get the

============================================================
Security Error: Domain Name Mismatch
You have attempted to establish a connection with "ipostoffice.att.net".
However, the security certificate presented belongs to
"ipostoffice.worldnet.att.net". It is possible, though unlikely, that
someone may be trying to intercept your communication with this web site.
If you suspect the certificate shown does not belong to
"ipostoffice.att.net", please cancel the connection and notify the site
administrator.
[View Certificate] [OK] [Cancel] [Help]
============================================================
Now, of course, I confidently click the [OK] button, but I'm wondering
if there's a way to program SeaMonkey to ignore this particular error
from this particular site, so I don't have to intervene every 20 minutes
whenever SM tries to get mail.
Thanks.
The CN on the certificate (which happens to be ipostoffice.worldnet.att.net)
needs to match the name of the host you're accessing (which happens to be
ipostoffice.att.net) or you'll get this warning.
If AT&T told you to use "ipostoffice.att.net", then they're certificate is
configured with with the wrong name.
However, notice that both host names point to the same host (ping both
names, and you'll see they evaluate to the same IP address) - so you
can just change the host name you're using to the one expected by the
certificate (ipostoffice.worldnet.att.net) and the warning will go
away.
If AT&T told you to use the other name, however, then I would expect
this to work only until they correct the certificate with the proper
value.
You're not familiar with AT&T, are you? Hell will probably freeze over
before they change their certificate. I would vote to change the host
name in preferences, etc..
I use AT&T for my landline. I used to be a Worldnet user but have since
gone to cable modem. So, I'm not the brightest bulb in the box. ;-)
