On a related topic, netzero.com has been refusing connections from our SMTP servers. When I queried them the response I got was:
have been blocked because we detected probe attempts. Activities like sending mail to non-existent accounts or empty connections would qualify as a "dictionary search" or "probing for valid addresses" and IP's used for such activity would be automatically blocked for a temporary period. Subsequent communications have dealt only with the non-existent accounts. Does blocking us on this basis make any sense? And has anybody else encountered similar issues with netzero? If so, how resolved? In their favor, they did at least respond to me. And it doesn't appear to be a robot (or if it is, at least an intelligent one) as it entered into a sort of a dialog. This is better than other s who either don't respond ot use a robotic response. Among these are yahoo.com, aol.com, bellsouth.net and charter,net. I list these here not as a form of criticism as I accept the possibility that we may have something configured incorrectly or sub-optimally. My real aim is to find other postmasters who have had similar problems with these (or other sites) and discover from them what it is we may need to change.

Depends on your MTA, with postfix you could for example use "luser_relay". But I strongly advise AGAINST this idea, since every typo'ed address ends up being learned as spam. -- Ralf Hildebrandt (i.A. des IT-Zentrums) [EMAIL PROTECTED] Charite - Universitätsmedizin Berlin Tel. +49 (0)30-450 570-155 Gemeinsame Einrichtung von FU- und HU-Berlin Fax. +49 (0)30-450 570-962 IT-Zentrum Standort CBF send no mail to [EMAIL PROTECTED]
