The new release offers a basic SOCKS5 module and the option to filter emails through external commands in the POP3 module.
Also, various bugs have been ironed out.
I've re-uploaded the 1.4 package, as I've forgot to include the PAM directory in the previous one.
Sorry for the inconvenience.
mod_pop3 was only working as transparent proxy, as I've forgotten to implement the explicit proxy part before releasing it (and I did know I was forgetting something, mind you).
Anyway, now it works as stated in docs/mod_pop3.txt
The new release of prometeo fixes transparent proxy for all the modules, implements SSL tunneling in mod_http and features a new POP3 module able to filter mails through SpamAssassin.
The new release of prometeo contains several changes to the HTTP module.
In particular, stability has been improved and filters to block popups and browser resizing have been implemented.
This new release of prometeo fixes a potential crash when zlib is not available but gzip encoding was enabled in mod_http.
An initial release of proemeteo is available on http://prometeo-proxy.sourceforge.net
It's not listed yet in the file section, as I'd like to receive some feedback before doing a proper release.
So, if you think you need an HTTP/FTP/SSL proxy, please check it out :)
