On about the dozenth communication back-and-forth with my hosting company, they suggested that I change the port setting for outgoing mail, and BINGO!, I could send again. I'm still waiting for an explanation WHY this happened suddenly, and what the heck happened in the first place!
I suspect this has something to do with the motherfucking spammers who have used various of my domains to "spoof" return addresses, even though the Spamhouse FAQs insist that they only block IPs and not domains.
Anyway, as of today, I can't SEND any mail from my main domain. When I try, I get this error message:
Needless to say, I hadn't changed anything and that this just was suddenly there. I tried looking up that IP address and it just shows up as an SBC address, so I was at first thinking it might have something to do with our DSL service (via SBC/AT&T/Yahoo!), but found that it wasn't related at all to our own IP. Unfortunately, the person I was dealing with at AT&T seemed pretty clueless (she had never heard of the ThunderBird mail client and seemed only vaguely aware of FireFox!), and kept wanting to mess with the settings in my e-mail.
An error occurred while sending mail. The mail server responded:
http://www.spamhaus.org/query/bl?ip=18.104.22.168. Please verify that your
email address is correct in your Mail preferences and try again.
I have been trying to get a hold of the tech service at the place that hosts my btripp.com domain, but they say that 22.214.171.124 has nothing to do with them either. I'm thinking that if the IP isn't part of our DSL service, and isn't part of the hosting company's mail service, I should just go to Spamhaus.org and use their automated removal thing ... except that they're rather adamant about NOT doing this if you're an end-user (they claim that removing it will make you liable for any subsequent abuses).
Now, of course, there IS NO WAY TO CONTACT SPAMHAUS, which makes it impossible to ask anybody anything, which is why I'm throwing out a call for help here. Anybody have any experience in dealing with this stuff ... or maybe have a secret e-mail that would reach somebody at Spamhaus.org???
