[Dovecot] Regarding Digest-MD5 auth

Hi,

I am writing a Pop3Client. I use dovecot server as POP3 server in linux and hMailServer in windows.

I was just testing digest-md5 auth with dovecot server.

I had an observation.

After server side verification, server sends a verification code to client. If this fails, how can client send the negative response or does it not exist?

When I see packet capture, dovecot server sends +OK Logged in for anything client sends.

I may be wrong. Please let me know your thoughts
