hi,

I am just playing a bit with the dovecot SASL plugin for postfix and so far my tests have been very successfull, can't wait to get the cyrus-sasl beast replaced.

However, I found a potential problem when doing some "illegal" stuff on the postfix side:

-------CUT------- cerberus:/var/log# telnet smtptest 25 Trying 192.168.99.99... Connected to smtptest.bestsolution.at. Escape character is '^]'. 220 smtptest.bestsolution.at ESMTP Postfix (bestsolution.at GmbH) EHLO localhost 250-smtptest.bestsolution.at 250-PIPELINING 250-SIZE 51200000 250-ETRN 250-AUTH PLAIN DIGEST-MD5 CRAM-MD5 250-AUTH=PLAIN DIGEST-MD5 CRAM-MD5 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN AUTH somestring 535 5.7.0 Error: authentication failed: Connection lost to authentication server -------CUT-------

dovecot logs this:

-------CUT------- dovecot: Apr 27 10:27:36 Error: auth(default): BUG: Authentication client 4315 requested unsupported authentication mechanism somestring dovecot: Apr 27 10:27:36 Error: child 445 (auth) killed with signal 11 -------CUT-------

I am very aware that "AUTH somestring" is not valid in the given context, but dovecot should not sigsev IMO.

dovecot is 1.0-beta7.
