Created attachment 378996 [details] sample bounced email Every email I've sent today to email@example.com has bounced back to me. The bounce comes from dm-mailman01.mozilla.org It reports that some MTA named mail.bcn.mythic-beasts.com has rejected the message. I wonder if mail to gerv is really supposed to go to mail.bcn.mythic-beasts.com
firstname.lastname@example.org just forwards to one of gerv's private addresses... I checked the MX of the domain it forwards to, and the MX is indeed mail.bcn.mythic-beasts.com, so yes, I would assume mail is really supposed to go there.
Maybe the mails from bugzilla will get through, even though the mails from me did not, and Gerv will find out about the mail problem, and be able to do something about it.
I have learned that my mail service provider's (MSP's) MTA thinks that the MTA at 220.127.116.11 (which is mail.bcn.mythic-beasts.com) is a spammer, and so evidently my MSP's MTA refuses to honor any connections from it for any reason. I gather that when I send my emails to Gerv, My MSP's MTA sends them to mozilla.org, which redirects them to mythic-beasts. Evidently when it receives the RCTP-TO envelope header for the email from mozilla, mythic-beasts attempts to contact my MSP's MTA, and when that attempt is effectively refused, mythic-beasts then refuses to deliver the email. http://unblock.secureserver.net/?ip=18.104.22.168 is a web page that someone from mythic-beasts could visit to try to resolve the spammer accusation.
I just midaired with Nelson, attempting to post this (which basically came to the same conclusion he just did). Based on the bounce message it looks like Nelson's mail server is rejecting Gerv's mail server when it tries to do a sender callback to verify that Nelson's email address exists. The bounce message implies that Gerv's mail server is on a spam blacklist that Nelson's server uses. Gerv's server refuses to accept mail from people it can't send mail back to. I'm resolving the bug, as it doesn't have anything to do with Mozilla, but you can feel free to communicate with Gerv here until you get this resolved. :)

Nelson: I got the test mail you sent about 20 minutes ago, but I can't reply to you. I get: This message was created automatically by mail delivery software. A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed: email@example.com SMTP error from remote mail server after RCPT TO:<firstname.lastname@example.org>: host smtp.where.secureserver.net [22.214.171.124]: 553 Bogus helo b. <http://unblock.secureserver.net/?ip=126.96.36.199> ------ This is a copy of the message, including all the headers. ------ Return-path: <email@example.com> ...

Gerv, The fact that the problem has resumed tells me that, after mythic-beasts got themselves taken off of some RBL, they got put back on it. My guess is that they've got a spammer sending spam through one of their servers and they don't know it. secureserver.net is Godaddy's set of SMTP and IMAP servers that use TLS. Mail service over TLS is a premium price service, and it uses separate servers (from Godaddy's normal email servers) that live in that domain. Godaddy seems very serious about stopping spam. BTW, The page at the URL cited above lists the 4 different RBLs that Godaddy's servers consult.
Just FYI, I did try a couple of the multi-listing lookup services on mythic-beasts' IP address when I was looking at this the other day, and didn't find any hits at all for that IP on any of the common blacklists out there. (Godaddy's list that we know it's on isn't included in any of those lookup services).
Mythic Beasts is a small company run by highly competent people, two things which makes it in the "least likely" category to have its servers being used by spammers. They are also highly responsive, in person, to requests for support. Here's the email I got from them at 10:09am UK time on the 22nd: "Hi, That mail server was briefly listed on the barracuda black list earlier this week but has been unblocked for several days now. I've done a blacklist check and of the 147 commonly used blacklists we aren't on any of them. If he could find out which blacklist he thinks we're listed on we'll try and investigate, the secureserver page he linked to doesn't seem to be attached to any blacklist and looks like a spam site that gathers email addresses. If you can confirm the blacklist that's blocking us, we'll happily attempt to resolve issues with them. Pete"
The obvious way for mythic-beasts to resolve this is to use the form provided and communicate with Godaddy at secureserver.net.
I'll vouch that secureserver.net == godaddy.com's hosting division. I used to have stuff hosted with them before I switched to Dreamhost for my personal stuff. I'll also vouch that GoDaddy's hosting folks aren't exactly responsive and their business practices are just shy of being shady (among the reasons I quit hosting there). Although it's been 4 years or so since I left them, and a lot can change in that time.
