[Dovecot] Check plugin loading for LDA and dovecot-sieve

Hello,

I found this thread: http://www.dovecot.org/list/dovecot/2006- September/015955.html

and have successfully compiled and installed cmusieve plugin. How
does one test to make sure its being loaded? It's not parsing my
sieve files in the users homes and I'd like to first check if the
plugin is being loaded, since I am getting no errors about it.

Thanks
