Part of the OP's original issue is that with the default SMTP_MAX_RCPTS = 500, messages delivered from Mailman to Postfix had hundreds of Hotmail (and/or Yahoo) envelope recipients. Postfix would apparently then deliver the message to Hotmail, again in one transaction with all the Hotmail envelope recipients, and Hotmail would not accept an envelope with that many recipients (and similarly for Yahoo). Probably, SMTP_MAX_RCPTS could be larger than 5 and still avoid the problem, but it probably can't be more than 20 or so. Of course, the real solution is for the OP to negotiate with Microsoft and Yahoo and maybe others to get his server whitelisted if he can. -- Mark Sapiro <m...@msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
