I have read a number of posts about configuring the POP3 proxy. I have also read through the manual. But I am now at wits end trying to get it to work. There seems to be very little to do in the UTM settings which is all the more frustrating from a troubleshooting perspective.
I am running UTM 9.004-34. I am trying to connect to my ISP to retrieve email through POP3 without SSL (using port 110). Without POP3 proxy enabled, I can connect and retrieve email no problem.
For the POP3 proxy, I have enabled it (Email Protection->POP3->Global). I have also set my internal network in allowed networks. For the moment, I have left AntiVirus, AntiSpam & Exceptions at defaults. Under the advanced tab, I have added my ISP POP3 server under POP3 Servers.
In my email app, when I retrieve email, it tells me:
"The server returned the error: The server “my ISP POP3 server" refused to allow a connection on port 110."
Now this is the error no matter what changes I make in the POP3 configuration on the UTM. I understand the POP3 to be a transparent proxy, so I had my email app pointing directly to my ISP POP3 server. But I have also tried pointing the email app directly at the UTM IP address, with no change other than instead of complaining that my ISP POP3 server refused the connection it lists the UTM IP address.
In a nutshell, the UTM is effectively blocking port 110 when I turn on the POP3 proxy.
Oh yes, in the POP3 proxy live log, this error message appears:
"2013:02:24-11:47:56 ***X pop3proxy[11670]: Can't connect to database, retrying in 10 seconds: could not connect to server: Connection refused"
Any ideas?
