Hello folks; On this system, I run a Listserv list called Help-Net. It is very busy. One of my colleagues got the bright idea to set up a ccMail server for our department here at Temple. This was done about a month ago. The ccMail package has a bulletin board feature on it. Our ccMail administrator created a bulletin board on our ccMail server called #Help-Net. The host name for this server is compserv.ocis.temple.edu. I added a subscription entry to my Help-Net list for this bulletin board as [log in to unmask] The # symbol in the address is apparantly required by the ccMail package. As soon as I did that, the bulletin board started receiving Help-Net postings. This was fine for a little while, however, after a recent network configuration change (we installed a router for our department's ethernet segment), Help-Net mail sent to this address by Listserv started to bounce with unknown host messages. The network people here fixed that problem and things seemed okay for a few days. Now, for the past few days, every other posting or so from Help-Net gets bounced by our mailer with a host unknown message for [log in to unmask] I won't include a sample bounced message here because all it says is that the host compserv.ocis.temple.edu is known, however, a post that might come in for Help-Net a few minutes before or after a rejected one gets to the host without a problem. This is very confusing since the problem seems to be intermittent over the course of a very short time. If anyone has any suggestions on what might be going wrong, please let me know. Our network also people say our network is fine and that the problem must be on our VM system, but none of the other 1000+ subscribers on Help-Net seems to have a problem getting mail, at least, not like this intermittent situation.
