SBC filtering Outgoing eMail

By mthomp ·
I just found out (the hard way) that SBCYahoo DSL lines are filtered on port 25 IF the email server being addressed is not one of THEIR email servers. What that means is that if I am using one of their DSL lines and I'm using my company's email address through Outlook (Express) or some other POP client that happens to be hosted somewhere other than an SBC email server, then I can receive email, but I cannot send email. All my sent email just gets stuck on my own computer and goes nowhere.

I just spent several hours with a client trying to figure out why their email suddenly stopped going out. It turns out that SBC unilaterally made this policy up about two weeks ago without telling anyone or informing any existing clients. Then when clients call the help-desk-in-India, the person goes through the usual its-your-problem routine. If I hadn't had my ducks lined up when I called, I don't think he would've told me that they were filtering port 25 traffic -- supposedly to try to control Spam through their system.

Now, to me this is akin to burning the house down to get rid of the termites.

They do have a form that I had to fill out to request that filtering of our domain be removed from their server, but if I hadn't complained, I would never have known about it or found it. SBC, as far as I know, has no plans to inform their customer base of what they've done. I guess Ma Bell still knows what's good for all of us.

I have already recommended that the client change DSL providers. What's your take?

I'm not in an SBC area but it took me all of 5 minutes to find this;

If I'd known to look for it, I might have found it. The main irritation to me was that they just shut off the port without telling existing business clients they were going to do that. The company I was dealing with has virtually no technical expertise of their own - very small. So was their in-house wiring broken? Was it their domain host who also hosts their email? Those are the normal places you look first.

I don't fault SBC for defending themselves against Spam. I do fault them for their heavy-handed tactic and "don't care" attitude.

You found the form because you knew to look for it. If you didn't know it was broken, then you wouldn't have gone looking for that particular problem since port 25 has been open up until a couple of weeks ago.

Pretty much explains everything about them.

My appologies if I came accross too negatively.

No, not informed

by Cactus Pete In reply to Not informed?

Posted on the internet under that Help section does not inform the users ahead of time. They will only get there if they experience the problem - This does not permit them to plan ahead of time, does it?

And most of the users will not think to look there, I bet... Not exactly the best communication skills...

Quite right

by jdclyde In reply to No, not informed

When I moved off my cable modem, that was faster than my DSL it was mainly because they stated they didn't block ports.

To pull this crap without a notification of some kind is so much BS.

Who do they think they are, M$?

Ran across this too.

We have ~500 email clients that must for compliance reasons send through my server. It is the only way I can trap their outbound emails to comply with company and govermental regs. Now these policies will force the clients to one option only, use our web interface.

Sucks, but more ISPs are starting to do it.

Problem is the solution won't work

by mthomp In reply to Ran across this too.

The "solution" is both short-term and short-sighted though. There's another option for many small companies, albeit a painful one, and that's to change broadband carriers. You can make that policy within your company and make it work. But for a "public utility" like SBC to pull a stunt like this is a completely different matter. Even opening up different outbound ports is only a short-term fix, though I'll admit it does work most of the time -- but only for now. The spammers haven't proved themselves to be stupid so far.

SBC is being jerky, and I think the person who pushed the button on this one should be let go because of the poor, knee-jerk way it was handled. Won't happen though, I know...

Not the only provider doing this

by TheChas In reply to SBC filtering Outgoing eM ...

I have never been able to send mail from any account other than the one I was directly connected to.

This has been true with both dial-up accounts I have had and my SBC DSL account.
