Ten to fifty users is actually quite a lot. You're not likely to get too much more than this, because a lot of MTAs on the Internet are configured to refuse to accept messages from you if you've got too many recipients. Some of these sites set the limit as low as ten users, some set it higher (like fifty or 100). In your case, turning on personalization and VERP may actually help your message delivery because you won't be triggering such limitations, and you'd have a better idea of which recipients were causing problems for you. Even though this would reduce the number of recipients per message, the end result may well be an improvement. > ****Apr 17 09:30:30 smgpub sendmail[27208]: m3HD1x7v027207: > to=<[EMAIL PROTECTED]>, delay=00:28:31, xdelay=00:28:31, mailer=esmtp > 9147447, relay=relay.bu.edu.

You need to fix your sendmail configuration, or talk to the people at the remote sites and find out why they're causing such huge delays.
