It's default is 2048 (> 25 addresses) The big mail handlers like Yahoo will not allow more then 25 addresses per envelop or more then 4 connections at the same time. Most important is to keep your list clean. If you get a large number of rejects the big guys will throttle you back to far less then 4 connection and 25 addresses. Regards, Pete ---- Peter P.

We use the program bulk_mailer to group domains together in SMTP envelopes, but larger lists with lots of Yahoo addresses for example get rejected due to too many recipients. We tried adjusting sendmail max messages per envelope settings, but these seem to just reject entirely and not break up the envelope... Ideas? Rob
