Dear users, mail server administrators and affected people,

For quite some time now (spanning over more then a year), spam is being relayed through lists hosted by

I do realize this action affects the operation of, but I think this is a neccessary step to protect users against this form of spam, and the ignorant blind behaviour of has tremendously contributed to this situation.

Something very strange here, I am a user and am having trouble with only one email addresses. No other emails get rejected.

@Milton Kessler
As you can see, they do now, although the comment entry is older

@Bob Burnett
It depends on the receiver if he accepts mails or not in case he utilizes our list or not. It could also be the case that they shifted the IP's of the outgoing MX servers to NOT use these.
You can test this by sending a mail from your based account to any other mail account you might monitor and check it's headers.

Are you still seeing any further issues from our network?

Update: received mail from elvin today, pointed him to this blog entry. This also clearly shows he has not read any replies from his request, nor does he even seem to remember the last time he was in this situation.

After two years, the issue still persists, so I added the MX'es again.
