This bug can be fixed by adding a "close(fd);" in src/auths/dovecot.c.
Without the close()-call Exim does not shut down the connection and a
subsequent connection (announcing the same client PID during
handshake) will fail. You'll most likely see the above warning message
if a SMTP client tries multiple auth mechanisms with a wrong password.
Would be nice to have this fixed upstream in the Exim source.
