Some collegaues inform me that they cannot receive mails from some vendors.
But they can send mails to the vendors. Thus, I start to find out the
problem. I have packet capture tools installed on the exchange server to
monitor the SMTP communication between the servers. I found that incorrect
respond from our server:
Vendor server: [SYN]
Our server: [SYN, ACK]
Vendor server: [ACK]
Our server: [FIN, ACK]
Vendor server: [ACK]
Vendor server: [FIN, ACK]
Out server: [ACK]
Then the connection will be closed. Please help!!!
