Dreaded 522 error NDR :(

[Diakatarnis]

I think i have this problem:

http://support.microsoft.com/Default.aspx?kbid=885419

I'm a bit unsure as to whether this is a problem on the Recipients server or the senders server (mine)

Ive done all the latest updates etc, the hotfix wont run on the server as its sp2 and the fix is only for SP1.

I've added the registry DWORD which hasnt been tested yet. Anyone have any ideas?

I'm using postini to filter the spam if that helps?

Many thanks

Ben

Post the NDR and check the recipient address using:

http://centralops.net/co/EmailDossier.aspx

Also, manually connect to thier SMTP server from your desktop or something directly online and try to send a mail:

telnet thierip 25
HELO yourdomain.com
MAIL FROM: <[email protected]>
RCPT TO: <[email protected]>
DATA
Test
hit return hit return

If that goes out, then its an issue with your Exchange/Mail filtering as opposed to them.

Its really weird, Some emails go through, others get NDR'd The email that was causing a bounceback was sent to my server (exchange) and it arrived fine.

So im stumped agian :S
