We have a customer on a 64 kbits leased line (doan laff, that sh*t's expensive in France), running Exchange. We have our DNS set up so that incoming mail is preferably delivered directly to him: hisdomain.com IN MX 5 exchange.hisdomain.com hisdomain.com IN MX 10 mailserver.ourdomain.com Also, we relay all his outgoing mail, so we've got his exhcange.hisdomain.com and hisdomain.com in our NT hosts file, and his exchange set up to send all his outgoing to mailserver.ourdomain.com. His overall mail delivery works fine, but we see many instances (using my IMDeliver www.MEIway.com/IMDeliver log extractor tool) where our mailserver is rdeliver-ing to hisdomain.com, ie, forwarding incoming mail to him, meaning that our mailserver is working as his backup maildomain frequently. From everywhere and everytime I've pinged, nsuplooked, tracerouted, all is cool from Internet to his exchange.hisdomain.com and hisdomain.com. Also his company reports no pb's surfing all day over that line, so I'm fairly sure the leased line connectivity is solid. What could be the cause/solution for so many incoming Internet msgs being relayed through us rather than being delivered directly to him?
