Nathan, That is what I suspected, I only administer the server which runs LISTSERV and not any of the servers that connect it tho the trunk line, et cetera. This has happened before, but always all ports would go down. In this case it seems that just port 25 is out of commission. I'm contacting the other company that should know about the problem right now, but I couldn't locate the exact problem previously. Would you mind telling me what you did to test connections on port 25?
