Mail blocked by some domains
Some domains have decided we're spam and are no longer accepting mail from us. This is a temporary situation, and I am working on getting in touch with the right people to make sure we can get unblocked and deliver mail in a timely fashion.
Domains known to be blocking at least some of our mail:
sbcglobal.net
att.net
earthlink.net
It's kind of hit and miss. We have four IPs that we send mail through and they blocked two of them. The other two remain unaffected. Of the two blocked, I have managed to get one unblocked through their automated system, but the other is still blacklisted.
I'll post again when I know more. In the meantime, if you use one of these providers and are having trouble getting mail, you may wish to consider temporarily using a different email address for now.

Dreamwidth.org sends mail on one of four IPs:
174.143.24.133 dfw-jobs01.dreamwidth.org
174.143.252.249 dfw-jobs02.dreamwidth.org
67.23.34.143 dfw-jobs03.dreamwidth.org
67.23.34.144 dfw-jobs04.dreamwidth.org

Will switch and see what happens.

However, your DNS records are held by dyndns.org. I have heard of mail administrators refusing to accept mail from hosts whose name records are at a publicly-accessible dynamic provider. Perhaps that's an avenue you could explore.
The rejection messages in your logs should give you some clue (although knowing some domains, maybe not - I don't understand when administrators get coy about their reasons for rejecting mail).

The providers you've listed (plus comcast.net) are looking for the following:
1. An "MX" record attached to every mail server, even if it's outbound-only
2. A reverse DNS record attached to every mail server (this is critical!)
3. An "A" record in every "MX" record-e.g., don't put just an IP address in an MX record.
4. Every mail host answers up with its "A" record name. I notice that "mail.dreamwidth.org" answers up as "dfw-mail01". It should answer up as "mail.dreamwidth.org" -OR- you should change the mail server's MX record to "dfw-mail01".
If I can be of further assistance with DNS troubleshooting, please let me know.

I work for that ISP.
Nice to know there are more tech support people out there :)

1) Updated DNS as indicated, all outgoing mailservers now have matching MX record that points back at them.
2, 3) These were done already.
4) I changed the MX record to be dfw-mail01.dreamwidth.org, but the mailserver still answers as "dfw-mail01" (without the domain), does it HAVE to have the entire domain?

So my advice--which you are perfectly entitled to not follow if you don't want to--is to use the FQDN.

FYI, I had been dealing with similar last year. SBC uses AT&T stuff, not sure about earthlink; but AT&T maintains active whitelisting. Even if you have everything setup correctly, using the automated method often re-blacklists you every few weeks.
Let me know if you actually manage to get someone on the horn who can permanently whitelist you. I wasn't able to get the blacklisting stopped until we had our colo transfer the ip to us with ICANN.

"Please ask the sender to forward the bounce back message he have received along with the header information to the email address falsepositivereport@earthlink.net, and the IP address in the subject line once the sender send email message to the above given address, our Engineers will unblock the email address or domain with in 24 hrs."
I hope this helps.

Just FYI, at yahoo.com, both emails I've gotten from DW have ended up in my 'Spam' box. I've marked both 'not spam', so I hope that helps.

Other than that, I've had no problems. All my registration mail showed up promptly, and I'm getting notifications about posts. I thought you might appreciate a letter telling you some things are working properly!
I am glad I'm in control of my own email. I run my own email server on a computer in my basement.

I'm not sure why this is happening, since LiveJournal email alerts seem to be formatted the same way, but I was wondering if you guys knew about this and why it's happening, or had a fix coming up, or if it's even a problem on DW's end. It's just difficult sorting through comments not knowing where the comment came from because one email has 60 different replies from... pretty much every place I've commented.
Thanks!
