Thanks, John. Unfortunately I couldn't check my setup yet (I have to
modify my rather large exim.conf for that).
Timo Sirainen (Creator of dovecot) wrote on the Dovecot mailing list:
"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."
