I finally got confirmation from a CSR with AT&T/Cingular that they are
indeed blocking the user of outside smtp servers. Bastards. The guy
said that the server I'm trying to use is "not supported", and so they
"are blocking it".
cwmx.com takes frelling forever for mail to get through it. I've timed
it at a minimum of 30 minutes, and it's taken as long as four HOURS.

As in you can't access your own server (or anyone else's) while using the
handset or tethered or you can't use your own mail server on a tethered
handset? Just curious what you're experiencing.

As in I cannot use "my" own server from the handset. I have not
tethered to anything as of yet. And I don't think tethering or not
tethering would make any difference here. The cellular network is
blocking the connection to the outside server.
I'm trying to find out from my email provider if I can use an alternate
port.

Ok, as I understand it...you are trying to use your handset to check your
email. Have you tried other email servers? True, handset or tethered would
be a moot point.

From my handset, I have access to two SMTP servers: cwmx.com which is
unacceptably slow and "my" server at my mail/domain host which AT&T is
blocking.

Come join us at T-Mobile, Jeffrey!
T-Mo allows access to any e-mail server.
To be fair to AT&T, T-Mo has a weird setup if you want to use their
servers (for those e-mail providers that block SMTP access originating
outside their own network.) Unlike an "open" SMTP server like cwmx.com,
you have to register up to five specific e-mail address on their website
that you can then use the T-Mobile SMTP server with. (This wouldn't
apply to you, most likely, since you want to use your own anyway.) They
issue you a new username (your phone number followed by :1, :2, etc. up
to :5 for the five e-mail accounts) which you use with your existing SMTP
password.

It's not unheard of for ISPs in general to block outbound port 25 access,
or to redirect it so that it goes to their own servers. It's an anti-spam
measure. See if port 587 will do you any good.

Interesting. Did CS say it was a blocking model across the broad or unique
to you. Keep us posted on what you find out.

"That server is not supported. Use cwmx.com port 25 instead."

I think Hotmail is one of several email accounts that supports
'aggregating'. A free Hotmail account should be able to collect emails from
multiple accounts then present them as online accessible.
You didn't mention what device you are using. I use WebEx to access my home
PC from a 8525 with an external monitor. I haven't tested the Blackjack.

It works for me. I'm using a V557 through Cingular (AT&T) MediaNet to
connect to my own personal mail server with IMAP and SMTP. No
problems at all. I just sent myself a test message to make sure it is
working.
Very highly likely this is a problem with your ISP. Most, if not all,
block use of their SMTP servers by outside IP addresss. If you're
lucky you can use SMTP authentication and it'll work.

Not the problem. I've specified OUTGOING mail as the problem, several
times.

It's a host, not an ISP. It works fine from my desktop. I've checked
with the host and they're not blocking anything. And the AT&T rep has
confirmed that +they+ are the ones blocking it.
All as I previously stated.

Are you connecting to a web mail service from your desktop or an SMTP
server with an email client on your desktop?

Except that they're not blocking anything. It works for me right
now. No problems. No blocked ports.
On the other hand, I would *not* be able to connect to a Comcast SMTP
server with my phone even though I'm a Comcast customer because they
block external IPs. But I own my own mail server.

They are not my ISP, they do not provide my connectivity. They provide
my web, mail, and domain hosting.

SMTP. The only way to fly.

Since the server I'm trying to use is NOT provided by an ISP, rather by
a hosting service, the only way to access it is via an external IP.
This server is not being blocked at the host end. Other users have
confirmed that they can use it over their cellular connections. And as
I've stated in my OP, an AT&T rep has confirmed/admitted that they are
the ones doing the blocking.
