[Dovecot] How to find an invalid configuration in dovecot.conf

[Laurent PELLISSIER]

Hi,

I'm trying to test Dovecot as an IMAP ans POP3 server but I ran into a 
fatal problem.
On the client side (telnet) I'm trying very basic IMAP commands :

$ telnet localhost imap
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.
* OK Dovecot ready.
1 LOGIN lavande secret
1 OK Logged in.
Connection closed by foreign host.

The login succeeds but the connection hangs !


On the server side it complains that the configuration file dovecot.conf 
is invalid (it was copied from dovecot-example.conf) but it never tells 
what line number is incorrect. dovecot -a or dovecot -n doesn't complain 
about a syntax error or something.

It works for POP3 for the same user/pass.


# /opt/dovecot/sbin/dovecot -F -c /etc/dovecot.conf
