I'm getting rather pissed at diverse wiretap legislations making the global rounds (lately EU is making noises towards storing a one year deep FIFO of all email and browsing traffic for all users), and would like to run my own MTA, with MX fallback to ISPs. I would like to have secure MUA-MTA (IMAP/SSL POP/SSL and MTA-MTA (if the other end supports it).
If anyone knows of patches which automatically query keyservers and GPG/PGP encrypt emails to targets (this is not a deep paranoia setup, just a cheap measure to increase encrypted mail traffic) that would be nice to have, too. 1) Out of Postfix and Exim (no qmail, please), which is the MTA scoring highest on crypto support? 2) Can you give me pointers to suitable crypto patches for above MTAs? TIA, Eugen
