I am hoping that someone can point me in the correct direction. I am running a backbone listserv on VM (v 1.8a). We have installed our own smtp mail system, but listserv sends everything to the next in line listserv site. That site is then processing the maile. I have one list that processes 60 to 70 submissions a day and the distributed mail to the next listserv is for 270+ . This is causing problems with there smtp mailer, as they are also the main entery point to this country. We have made all the modifications that they requested, but have not fixed the problem. Now they are going to loop all traffic back to the list owners. At this time, I have set Mail-Via= Distribute and Default-Options= SHORTBSMTP Any other ideas or places to look. Al
