Thanks fo the reply. I've re-compiled it with mysql support and since, the previous error is gone, however, I can now recieve mail fine, but SMTP authentication is not working, with the following error:
warning: SASL PLAIN authentication failed
warning: SASL LOGIN authentication failed
My email client just keeps asking for the password, in which, it fails to authenticate everytime.
