Hi, list folks. Be gentle. This is my first time! We operate an email list server that dispatches e-mail newsletters for various clients. We are using a perl script called "Subscribe Me" to blast these mailings out. The Subscribe Me perl script simply reads the email addresses from a list, and one at a time invokes sendmail to dispatch them. We were running RHEL 3.0 ES on an Athlon 1Ghz machine. Shortly after 4.0 was released, I downloaded it and did an upgrade, which went without incident. After the upgrade, we noticed that the mail blast machine had gone from dispatching 4 to 5 emails per second, to one email every 4 to 5 seconds. A DRASTIC slowdown. There are no errors anywhere in the logs. DNS and Sendmail all seem to be working as usual, but for some reason that mailing script has slowed to a crawl. I attempted using renice to increase the priority of the perl script, which had no effect. I also made sure my sendmail.cf was the same, even remaking the .cf file from the M4 file. No change there. I know there were many changes from 3.0es to 4.0es. Is there an all-inclusive "changelog" between versions anywhere? Also, do any gurus here in-the-know have any suspicion why our e-blasts have slowed so dramatically? Thanks for your assistance. PS: Just so you can answer with a clear conscience, we're not a spammer - we operate several web sites for bands that dispatch messages to their fan lists. :-) -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
