| Rejected E-mail from improperly configured servers!
Like I stated in an earlier post, the only e-mails being rejected are from mail servers that do not follow the RFC's. They do not have the proper MX and/or A records setup. Anyone setting up a mail server has the responsibility to follow the rules. I'm all for the actions AT&T have taken to help stop spam.
When I implemented the DNS checking on my mail server it blocked 80% of the junk mail.
Mail admins need to do it right or don't do it at all! |

| I run the same mail server yahoo runs - Zimbra. And I know how it behaves and know what happened when I implemented them DNS checks in my mail server. It shut down a lot of spam plus blocked mail that was coming through that was not spam, just from improperly configured servers. I guarantee you this is what is happening. |

| One of the most amazing facts was the number of large companies whose IT departments are obviously not up to the challenge of administering their mail servers. When a mail server answers the helo command and it is not what the MX record shows or may not even have an MX or A record, it is rejected. It is such an easy thing to get right and spelled out in the RFC's. |

So you are just guessing based on a mistake you made. OK then.
Still waiting for evidence the datacenter is not being run by a bunch of drunken ferrets.

| What mistake did I make? My server is doing what I told it to. Block anyone who doesn't know how to setup a mail server. That is just what AT&T and the rest of the legitimate mail servers are doing.
Only improperly configured servers are being blocked - period! |

Obviously you know nothing about setting up a mail server, or DNS or how a mail server even works! |

| Well, if it makes you feel better to hurl insults, then go right ahead. I'm a big boy and I can take it. You just go ahead and play with your toys. Period!
I'm also an AT&T Yahoo! customer who has been putting up with this absurdity and I can assure you that a fairly good sample of emails being bounced are fully RFC compliant. I know enough about setting up a mail server, DNS and how it all works to know incompetence when I see it.

Mcalester, OK | You are simply wrong but if it makes you fell better to bas Yahoo, go ahead. I guarantee you the rejected mails are from non-compliant servers. |

Chicago, IL | I am cashing in on that guarantee. AT&T officially admits they screwed up. What do I get for my trouble and missed billable hours tracking this little annoyance down?
