Either buy more bandwidth or host your list server external and let them worry about bandwidth. Problem is not exchange/VS or listserv, but bandwidth. The fact that a connection is open for a long time is irrelevant. What is transferred over the connection is relevant. Say a connection is open for 2 minutes, the email data is transferred for the first minute and then nothing happens for the next minute , a timeout occurs and then the connection is closed. The bandwidth taken up is effectively for the first 1 min not the subsequent second minute.
HTH cheers Dean >>> [EMAIL PROTECTED] 12/05/2004 1:33:39 p.m. >>> COX Cable. 1.5Mb down, 512k up. They're "supposed" to pull fiber in this summer but I'll believe it when it's done. I think I know what caused the problem (all cleared up now) but I still have a couple questions for the experts. When the listserv emails were relayed by the SMTP VS, the VS opened active connections to the remote servers to deliver the mail (normal) but the connections remained in an active state for quite some time before going back to "ready" and finally being removed from the queue list, at which time I noticed we were back up to speed. Is there a place to set timing on the VS so the connections get reset faster? Rebooting didn't reset them and disabling them didn't seem to help so they must somehow still be active until such time as the VS is either stopped or they finally timeout. Basically they sucked up all my bandwidth. What it comes down to is I either have to get budget to greatly beef up the exchange server to handle the listserv traffic or budget to purchase Lsoft's LSMTP server to run with listserv and bypass my exchange server completely, unless someone out there knows of a different/better way to do it. I've heard there's a way to do it with Linux but I've never exposed myself to L yet. And to answer Andy David's question about the mailguard feature on the PIX, the PIX configuration was handled by a consultant until I can become familiar with it's features/programming so I don't know if it's enabled, but I will ask. Should it be?

This server relays mail for our ListServ server which previously worked fine (relaying is set up for only our listserv server) This morning we sent out some listserv emails (more than normal) and everything seemed to work ok except our access to the internet slowed down to the point that pings timeout or show 2300+ms. I've got it down to where if I stop the SMTP virtual server, all internet access comes back up to speed. Pausing the VS has no effect. The outbound queues (155 of them) are mostly in an active state with 16 on retry. Disabling all connections and freezing all messages had no effect on internet access, only stopping the VS. For fun I restarted the server but to no avail. Our network itself seems not affected as speeds connecting to servers/shares etc. are normal. Diagnostic logging for SMTP wasn't enabled earlier so I enabled it (maximum) but so far haven't seen anything useful. Any ideas on what else I should check?
