Hi All,
What are the port numbers in SME 5.5 pop download for the external mail client?
I have currently one SME 5.5 running in Server-Only operation mode which is behind the Cisco PIX firewall, and all my external users are failed to access in the pop3 download even i have permitted 110/tcp in Cisco PIX.
My question are what exactly the protocols and the relevant ports for the SME pop3 download use to connect, beside the 110/tcp is permitted in firewall system, what other additional port is needed to concern in the SME?
[root@sme /root]# telnet 61.142.2.17 110
Trying 61.142.2.17 ...
Connected to 61.142.2.17 .
Escape character is '^]'.
Connection closed by foreign host.
[root@sme /root]#
Please advise.
Thank you.
