We are using a server-to-server dial-up connection. We have some connection documents for mail transfer and one database replication. On schedule it works fine. In my connection documents there is no schedule for Saturday and Sunday, but somehow the system is dialing in these days. I believe some other program is initiating a request to connect the servers. Whenever it connects, it pushes a mail request, even though there is no mail. Sometimes it is connected for almost 300 minutes at night. I am a developer and my Notes admin does not have any clue about this problem. Could you help me with things I can ask him to check?
One possibility is that the "route mail at once" feature is being tripped. This sends mail to the next hop, if there are more than X pending messages, where X is settable by you. But you said that there is no pending mail in these cases. So I don't have an immediate answer. If you would like me to take a look at this in person, I could probably figure out what is going on. Please e-mail me if you want to pursue this.
