Unable to connect using POP3S(SSL) from outside of firewall

Hi

I've been trying to figure out my problem for a while now but can't seem to find the problem. Hope someone can help me.

I can't access POP3(SSL) when I'm connecting to the server from outside the firewall. I even opend/allowed all access from outside network. But still the same.

But POP3S(SSL) is working fine if I access it from inside the internal network.

I'm using Ubuntu 8.04 and installed Virtualmin using the install.sh script.

Please help!

Well, it does sound like a firewall issue :-)

What error do you get when you try to access it from outside the firewall?

Do you see anything in /var/log/mail.log that suggests the request is hitting the server?

Hi Eric

Nice to hear from you. Thank You!

I get this message from outlook, 'Outlook is unable to connect to your incoming (POP3) e-mail server. If you continue to receive this message, contact your server administrator or Internet service provider (ISP).'

And there is no error log in /var/log/mail.log. So the request is not hitting the server is it?

Howdy,

Yeah, it sounds like the request isn't hitting the server.

POP3/SSL uses port 995 rather than 110 -- are you sure that port 995 is open on your firewall?

Yes I did opened port 995.

Maybe I'll check my firewall again.

Thank You for your help. Really appreciate it.
