I'm running several mailing lists and digests with 5000+ users and with that approach, since it goes out as one sendmail process, each transient failure will delay the rest of the list for 5 to 10 minutes. For example, I am running the GUS Daily Digest and that list has 2000+ users with the digest size being 20-30k once a day it goes out, it will take 17 hours to finish sending to everyone on a SUN SparcStation 5 on a T3 link on mail.nws.orst.edu since there are about 5% transient failures which delays the sending of the digest to the rest of the list for a couple hours since even though if you did sorting, it will still go out as one sendmail progress. What I did was used Keith Moore's bulk_mailer which I put for gus-general-digest-outgoing alias for majordomo to redirect to instead of sendmail since bulk_mailer will sort up to 10 domains for each sendmail process that it sends to sendmail so that you have several sendmail process running at once. This has made the digest take 30 minutes to complete instead of 17 hours. This was recently discussed on the majordomo-workers mailing list at GreatCirle.com. Hope this helps.
