Https & port 443

Hi there.

Current set-up:

ISPConfig 3 - latest vers & Debian Lenny

http://server.domain.com:8080 - ISPConfig
http://server.domain.com/webmail - Squirrelmail

Preferred set-up:

http://server.domain.com:8080 - ISPConfig
https://server.domain.com/webmail - Squirrelmail

I'd prefer that any non port specific www traffic be thru port 443/https

I have tried some of the previously advised solutions with out any luck.

Thanks.
