I posted the other day about an e-mail problem I was having and wondered outloud if it wasn’t just a glitch on my end but actually my ISP (SBC Global) blocking the ports I was using to send e-mails. The comments on that post made it very clear that it was in fact SBC blocking port 25 as many other people were having the same problems – and were equally appalled that SBC would do something like this without even mentioning it to it’s customers. Very bad business guys, very bad.
The good news it that it’s fixable. There’s a help page on SBC’s site that gives you some options, most of which are honestly bullshit. They want you to use their services but you shouldn’t have to do that. You could also use a proxy through another server but that slows things down considerably. There’s also a form you can fill out and request that filtering (blocking) be turned off for your account but who knows if and when they would get to that request or if it would be approved.
The solution that worked for me is something that Andrew pointed out as well, simply use a different port. Your e-mail program gives you an option of which port to use for sending e-mail and chooses 25 by default but you can change that to 26, or 2025 (those where the two that worked for me). As of right now I can happily send e-mail again from my house and I didn’t even have to deal with SBC to do it.
If anyone has any other solutions please post them in the comments and I’ll update this posts to inculde them.
