Re: PO ver 712 smtp problems

[john@xxxxxxxxxxxxxxx (John Sievert)]

Blackhole's can be tricky.  It really depends on the blackhole server 
that you are using - for outgoing, this would mean that your user is 
being identified as a spammer.

Some also felt that this could be pop before smtp going astray.
Restart and verify if the problem goes away.  Other than that you 
will  need to look at the blackhole thing.  To do this, I would 
suggest the  following:

1. figure out the ip address that this user was trying to send this 
from.  Go to http://relays.osirusoft.com/cgi-bin/rbcheck.cgi and 
check  that IP address in all of the DNSBL that they list (lots of 
them).  For  example, if your user was trying to SMTP in from a 
remote location on a  dial up from some ISP some DNSBL will block 
that ( a good thing).  This  could be one case.

2. modify your BL filter so that you have it as both discard and 
copyto.  Create a special account to trap these emails so that you 
categorically can say that this was the filter that did the nasty 
deed.

regards,
John
