I am also a Verizon customer, and my (possibly mangled) understanding
of the situation is:
- If you're using Verizon's mail servers as your SMTP hosts,
you can use port 25, and/but you must authenticate, and you
must use a "verizon.net" or "bellatlantic.net" from-address.
- If you are using a third-party mail server outside of the
verizon.net domain, and using SMTP to connect, then port 25 is
blocked, and you must use port 587 to connect to these systems.
Allowed "from" addresses and authentication requirements depend
on the server.
- If you're using a web-mail client (e.g. for gmail or yahoo
or whatever), then, again, no configuration changes are
required, since all the SMTP action is outside of Verizon's
You don't say what mail relay your ssmtp command is configured
to use, but if it's "outgoing.verizon.net", then you can probably
continue to use port 25 without difficulty, since you clearly
have a Verizon address.
I use kmail on Debian "lenny", and send mail via authenticated
ESMTP on port 25 to outgoing.verizon.net, and it's working fine.
It's remotely possible I'm misconfigured and will be sorry when
the switch-over hits, but I read the instructions carefully, I think
