[PLUG] Problems w/SMTP on Verizon DSL, none on Comcast Cable?

[Jason Costomiris <jcostom@jasons.org>]

At my place I've got a cable modem from Comcast.  My parents have 
Verizon DSL.  When reading and sending mail from my place (using 
Mail.app on Mac OS X 10.2.1), everything works perfectly.  However, 
from my parents' house, I can read fine using IMAP/SSL, but sending 
mail fails every time.

My mail server is running RH 7.3 with Postfix 1.1.11 with TLS and SASL 
support built in.  SMTP connections from my client to the system are 
done over TLS and authenticated using the SASL LOGIN method.  When on 
the Verizon DSL and connecting to the mail server, the connection gets 
established, and the DATA command *seems* to be fine, but eventually 
times out.  Of course, pointing to Verizon's smtp server doesn't help, 
because they only allow @verizon.net and @bellatlantic.net email 
addresses to use their mail relays.

Now that I'm back @ my house, everything's working normally.  Anyone 
know of issues with Verizon's DSL network and SMTP servers that are 
outside of Verizon's network?
