If you are using dovecot-test72 you can try and apply the attached patch.
Other dovecot versions I have no idea. (kindly always report the version
of the software you are using if you want help).
It will log every POP command.
Also for testing purposes make sure you disable all "secure" or TLS
connections made from clients. Thats is in client configuration.
We have had some confusing problems due to TLS certificates etc.
Cheers,
Jens
