stripping extension from domain name

Thu, 3 Jul 2014 06:29:06 -0400

I know that the "%d" parameter is for the domain. Is there any way to use just the domain name sans its extension.

EXAMPLE:

example.com ==> example

Also, I have a lot of logging going on in my dovecot log file. I want to limit it to just the barest amount, such as indicting what mail box mail was delivered to. Authentication errors, etcetera should only be shown if an error occurs. Is this possible?

Thanks!
