Me nejde o SSL ale TSL, predem se priznam ze v tom nemam uplne jasno.
Ale kdyz otevru mailbox pres mutt a sleduju komunikaci tak to vypada tak
ze se mi mutp pripoji normalne na imap port a po CAPABILITIES jde
command STARTTLS a pak uz jde vse sifrovane.

Po fetchmailu bych chtel to samy. Ale nevim jak mu to vysvetlit. Pri
vypisu komunikace jde vse vcetne jmena a hesla v plain textu. Kokal jsem
do RFC a podle IMAP4rev1 jsem komand STARTTLS nenasel takze je to zrejme
nejake nestandartni rozsireni imap od washingtonske university (z
balicku pine). Proto bych rad vedel jestli jde fetchmailu vysvetlit ze
ma pouzit tohleto rozsireni. 
To samy (nejaky TLS) umi i ipop3d z pine. A kolegove s KMailem proti
tomu serveru normalne sifrovane komunikuji. Ja bych se nerad vzdaval
fetchmailu (i kdybych ho mel patchovat).

jeste prikladam vypios z komunikace fetchmail -> mailserver
