POP2SSL: Connect unencrypted POP3 clients to POP3-SSL Servers

POP2SSL

Add POP3-SSL encryption to older email clients

Many older email clients don't support SSL encryption for downloading of emails from POP3 servers but many email providers are currently moving to more secure platforms with mandatory SSL encryption. POP2SSL connects ordinary POP3 clients to encrypted POP3-SSL email servers by providing a local POP3 proxy on your own server through which your old software can connect to POP3-SSL servers via unencrypted POP3 connections.

What to use it for

What you don't need it for

How it works:

POP2SSL installs as a windows background service and then works as a POP3-to-POP3SSL proxy server. You configure your email client software or POP3 downloader to connect to your own server instead of to the actual POP3-SSL server that you want to reach. Use "localhost", "127.0.0.1" or your own computer's network name here. Instead of IP port 110 you'd configure your client software to connect to the special IP port 1110 - POP2SSL works on that port by default to avoid conflict with other POP3 services. To tell POP2SSL which POP3(-SSL) server to actually contact you need to configure the user name field in your client software in a specifiy way: Instead of just the username use the format "servername|portnumber|username" (fields separated by the pipe sign "|").

For example you could configure your POP3 client to connect to POP2SSL via unencrypted standard POP3 using "pop.myserver.com|995|myusername" as the configured user name. That would cause POP2SSL to connect through to "pop.myserver.com" on IP port 995 (default for SSL POP3 connections) and log in as user "myusername" and then connect the two ends.
