Re: Tor server for port 443

I just want to add, that the preferred way for encrypted POP3, IMAP,
ACAP and maybe SMTP is to use the (old) standard port and issue a
STARTTLS or STLS to switch to an encrypted communication:
In addition to port 443, you might consider ports like 995 - used
for secure POP3 - and 587, used for secure SMTP on Gmail.
The RFCs "discourage" the use of separate ports for pop3s and imaps,
reasons are given the RFC2595.
There is even something similar to STARTTLS for HTTP:
So, please keep in mind: connections to ports 80, 25, 587, 110 and
others _may_ be encrypted as well (while 443, 995 may also just use a
crippled cipher suite and may be not efficiently encrypted after all).
Port numbers are just a poor choice to decide upon kind and
circumstances (secure / non-secure) of traffic. ;-)
