Both have pros and cons. Perdition does PO3, IMAP4, supports TLS and can proxy connections to different servers based on username. Horde IMAP proxy does only IMAP4, no TLS (you can emulate it using stunnel), however it can cache connections, making it very suitable for use with webmail applications (it will reduce load on the real IMAP server significantly, since connection between proxy and real IMAP server is preserved between page loads). -- See Ya'' later, alligator! http://www.8-P.ca/

You can use xinetd''s ''redirect'' feature to act as a proxy for about any tcp connection without needing to know details of the protocol. It should work fine for pop or imap. Or you can use stunnel to accept an ssl connection and proxy to the unencrypted service. This will also work with most mail clients. -- Les Mikesell lesmikesell@gmail.com

(I run it on CentOS 4.2 x86_64) As said by Aleksandar and Les, opting for one depends on the goal(s) you have for using a POP3/IMAP proxy.

We would like something that acts like httpd does with its reverse proxy. i.e. so we don''t have to have our mail server sitting directly on the internet.

If you plan to accept mail from roaming internet users you''ll also need to set up smtp authentication which means either letting the ''outside'' box have access to the passwords or also using stunnel to pass the connections through to the inside server. -- Les Mikesell lesmikesell@gmail.com
