If you are using sendmail set the TOBUFSIZ to 1024 (< 25 addresses). 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.

What is the best way around this then with Majordomo? 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?
