[Dovecot] Regarding Digest-MD5 auth

[kenja heramba]

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

Regards,
Heramba
