dovecot - Jul 2007 - Bug in Exim->Dovecot auth

Hi.

I'm using SMTP auth with Exim authenticating against Dovecot's auth
socket. My (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'm not sure where to report this bug, exim's or dovecot's mailing
list, so I'll try here first :)

Oups, sorry, of course it is not "my" excellent tool. The tool was
written by John Jetmore. Sorry for my bad english.

That probably means that the Exim code creates a second connection. Or
possibly closes the old one and then immediately creates a new one so
that dovecot-auth doesn't notice that the old connection had yet died.

In any case this could be fixed by having Exim use a single connection
for the entire life time of the process..
