I was looking at my mail.log, when I noticed that my accounts passwords are displayed in cleartext in the clearpasswd field. I'm not confortable with this since I use those password elsewhere on my system. Now, I understand that my passworld is sent in clear anyway, but If at least it could not be written in clear on the disk... Is there a way to avoid this?

Yes, set the log settings to DEBUG_LOGIN=0 in

/usr/local/etc/authlib/authdaemonrc

and you'll be fine.

Note: if you don't use TLS and SSL than your passwords will be send over the network in the clear as well.

Thanks that did it...

I know it is sent in clear anyway, but SSL connection is something I'll do soon, the moment I'm sure everything will be working the way it should...
