Exim 3.35 and some e-mail addresses

[Kordula Martin <kordula@kordula.de>]

Hi Debian fans!

Please CC to me, as I've recently un-subscribed to the mailing list.  Thanks!

I have Woody installed with Exim 3.35 and most everything seems to be fine, 
but I cannot deliver mail to an address like anybody@eds.com for 
example.  At least I get a return message from eds.com:

This message was created automatically by mail delivery software (Exim).

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:

  <mailto:webmaster@eds.com>webmaster@eds.com
    SMTP error from remote mailer after RCPT 
TO:<<mailto:webmaster@eds.com>webmaster@eds.com>:
    host ah.eds.com [192.85.154.77]: 550 5.7.1 
<<mailto:webmaster@eds.com>webmaster@eds.com>... Mail from 80.139.141.133 
refused by RBL, RSS, or DUL, please see 
<http://www.mail-abuse.org>www.mail-abuse.org, sender is 
<mailto:robert@kormar.net>robert@kormar.net



Somewhere somebody seems to be thinking I'm sending abusive mail.?
Mail to other addresses like hotmail.com or gmx.net and gmx.de arrive, but 
almost always as "junk mail", no matter what I put in the subject field or 
message body.

Does anybody have an idea what I need to do, to get my mail delivered 
properly/appropriately?

All help with this problem will be greatly appreciated!!

Thanks,
Kordula Martin
