We are working with version 5.0 with exchange connectors. Two domains
between this domains are placed ISDN routers. When the routers make contact
by ISDN is costs money. Sometimes this routers makes contact for a long
time. It's over when I stop the MTA service.
Is it possible that it is a bug in Exchange 5.0?
Who can help me for a correct answer or tip?
With kindly regards,
