Called ATT tonight. Got a very helpful tech with an @2WIRE.COM email address. He had me go into the router's firewall. I went and UNchecked SMTP "allow" and that stopped the block. He was confused. He actually went and checked on it and replied: "I apologize. I know the SMTP issue is counter-intuitive with our router. There was a change in the firmware for your device and the option is in fact reversed. The only thing I can tell you is that it is being worked on and AT&T will provide updates when available. Thanks again!"

Try REMOVING the check to ALLOW SMTP traffic. That permitted free flow. Also, this is on ATT UVERSE. Thanks for your posting here!

I can’t go to http://helpme.att.net/servabuse.php to opt out of port 25 because they are blocking all e-mails. Doesn’t att.net have another way to reach in this instance??

Thanks Enny, I just setup using port 587 and things are working so far.

I use also port 587 as normal smtp port. That is the message-submission-port. Some email providers may not support/offer that.

Ah! What a chronicle here. I just got off the phone with At&T tech support and am fuming as they said I will need to upgrade my account! I have had this account for a few years and recently started working on an SMTP program. For local testing I needed to send stuff to myself and lo and behold IT doesnt work. TRaced it to this port issue.

Now, when I signed up for DSL, they didnt disclose this at all. That I wont get all the ports! Is this legal? they can just take away ports at will? Why should I need to upgrade to a business account for a port?

I m PO!

I just got off the phone with AT&T Residential DSL Support. Apparently, Level 1 Technical Support representatives are trained to tell you that the Port 25 block is permanent, irreversible, and for your own protection (all wrong). I asked that my call be escalated to Level 2, who after waiting on hold for close to 15 minutes, were able to reverse the Port 25 block in about 90 seconds. After rebooting the DSL modem, all is well.

The AT&T FAQ says, port 587 should be used, which worked for me.

Set up new server at new isp. New isp was a tad slow setting up rDNS (2 days).

Sbcglobal BLOCKED all mail from new server due to no rDNS.

Upon request for removal (after setup rDNS) using the assigned request form, sbcglobal / ATT admins said "sure" - and promptly converted the lockout from "bad rDNS" to "spammer".

Since then, every request for removal gets a "we already removed you" canned response - and we're still blocked.

I propose we all play their game - implement reverse DNS lookup on every web page and mail server - and lock-out all sbcglobal and ATT networks. Serve up a page to the customers of those networks that spells it out - and directs them to contact their customer service department about being censored from the 'net.

Easy to implement - easy to reverse as soon as the creeps quit their silliness...

Oh god, I thought this was the issue. I just moved to a semi-rural area in Texas and the only service offered here is AT&T. I assumed I’d plug the computer in, and be able to send and recieve email from 5 corporate email servers (which I maintain at my office) — port 25 is blocked hey? I sat here for a long time and tried to think of a legitimate reason for them to block smtp ports. I’m going to miss Time Warner – and unfortunately the condo I just bought is wired for AT&T, and is locked down. No hope. I regularly get attachments in excess of 12MB, so I’m sure those would be kicked back should I dare to use AT&T’s craptastic server. I guess I’m going to put that extra box in my office to work, throw our mailserver software on it, change the port and bounce just my mail off of it. I can’t really change the port on the servers themselves, as I have way too many clients in the field, and I don’t want to go there. =)

Why is AT&T so stupid?
