reduce memory usage?

[Lorenzo Musizza]

Hi all,
I like Cyrus Imap very much and I have it in production with thousands 
of users since many years.
Now I have a problem on one of my servers, since swap is being used (it 
is because I run other memory intensive applications and I can't upgrade 
memory), and I am wondering if there is something I can do to reduce 
cyrus memory usage, e.g. reducing thread number or something.

This is my actual memory consumption (if I read it correctly it is about 
300Mb?), cyrus version is v2.1.15.
