Last night I migrated my mail server using qtp-backup and qtp-restore. Everything went well. The server is sending and receiving emails just fine. My only problem is one scanner on my network will not connect to the server via port 25 to send out scanned documents. I've looked at everything. SpamDyke, SpamAssassing, IP Chains, IP Tables, etc.
I cannot find any reason why the server is rejecting all communications with this device. I even changed IP addresses twice and it still rejects its connection. My only remaining thought is that somewhere the devices MAC address is blacklisted or something. Any ideas out there? I feel like I've tried everything.
