[Dovecot] Problem with local pine after upgrade to 1.2.5

Hello,

I upgraded from dovecot 1.1.17 to 1.2.5. Works well so far with e.g. Thunderbird and SSL.

One problem left: pine doesn't work any more with rsh: cat .pinerc (filtered): rsh-path= rsh-command=/usr/sbin/dovecot --exec-mail imap

Starting pine: 1.) Opening INBOX 2.) [>SECURITY PROBLEM: insecure server advertised AUTH=PLAIN<] 3.) Afterwards I'm asked for a password: HOST: localhost (INSECURE)
ENTER LOGIN NAME [user] : 3.) cancel: [IMAP protocol error: Authentication aborted by client.]

Config: no changes at all.

Any ideas why this is broken?

Thnx.

Ciao, Gerhard
