I have just installed xeams. It is behind firewall, with private IP address. Ports forwarded properly.

Once I have changed MX record, and pointed it to the new mail server, I have sent 1 test mail, and received it in inbox x25 times, the same mail.

Note:

Good messages: 6

Outbound messages: 4

Inbound 6-4 = 2 (2 test inbound messages)

The chart show 48 inbound.

P.S. I can not attach images
