Re: 209.68.1.140 (209.68.1.0 /24) blocked by bellsouth.net for SMTP

Bellsouth basically told me they were blocking Pair Networks because
the percentage of spam vs non-spam is around 75 - 80%. They say
they are communicating with them on this. Supposedly there was a
conference telephone call this past Thursday 09-22-2005. BS says
they must reduce this spam amount for the block to be removed.

Pair seems to think it is mostly domain customers forwarding their
mailboxes to their BS dot Net email accounts.

Yes, this is quite clearly the case; there are dozens of mutual customers
who have forwarding rules setup.  We are not generating Spam to send to
Bellsouth; it's coming from somewhere else and then being forwarded.

I imagine that at some time in the future, forwarding e-mail might become
impractical, if receiving systems insist on parsing it as originated or
relayed Spam.

This the first I've heard of BS having a 50/5 threshold limit.

Bellsouth has given us no statistics, no logs, no headers, not even a
timeframe for their vague claims.  We can clearly see from our side that we
are not generating nor relaying Spam.  But our customers can no longer
choose to forward their e-mail to Bellsouth.  It seems that Bellsouth is
restricting its customers.
