Hi.

I'm using SMTP auth with Exim authenticating against Dovecot's auth
socket. The (excellent) SMTP test tool "swaks"
(http://jetmore.org/john/code/#swaks) tries multiple auth mechanismus
consecutively which leads to the following message in Dovecot's log
file:

Error: auth(default): BUG: Authentication client gave a PID 6738 of
existing connection

I've already posted this bug to Dovecot's mailing list, but nobody
replied. So I try again here.
