Retreiving email on my SBS2003 Server via Outlook Express and POP3
Posted on 2005-03-10
I want to be able to allow my remote staff to obtain email from their Exchange 2003 mailbox (on SBS2003) via POP3.
When I attempt to retreive email it fails with an error.
My setup is as follows:
NOTE: I have changed the public IP's for security but the sequence is the same.
SBS 2003 LAN IP=10.0.0.2 / SM=255.255.255.0
SBS 2003 WAN IP=188.8.131.52 / SM=255.255.255.240
Router External IP=184.108.40.206 / SM=255.255.255.240 (Assigned by the ISP as the gateway)
Router Internal IP=220.127.116.11 / SM=255.255.255.250 (Next number along from the above gateway - same range)
Router Port Fwd TCP Port 110 - forwarded to 18.104.22.168 (SBS WAN CARD)
If I attempt to collect email via OE and POP3 internally (on the LAN as a test) it works.
When I try it outside the company the following message is received by OE:
"The connection to the server has failed. Account: 'POP3TEST', Server: '22.214.171.124', Protocol: POP3, Port: 110, Secure(SSL): No, Socket Error: 10060, Error Number: 0x800CCC0E"
The interesting thing is that another installation that I have done works correctly, but not this one.
1) Any ideas on fixing this?
2) WHat is the best way to trace or diagnose this issue.
