It is, check the configure options.

Mine is aslo set to 10 minutes, so let it be so, I also enabled the 
lazyaw option and hoped that the memoryusage will dropp, but didn't see 
any changes atleast in dump file same all (Sender IP Sender e-mail 
Recipient e-mail Time accepted) there, for me the sender ip/mail is good 
enaugh.

Is so, then ok.

I'v have been using graymilter in some computers, with domain patch, as 
the original code accepts in initialwhitelist ip -s only, but since I 
need to whitelist whole country domain prefix, I can't use the original 
code.

Havent notice leak yet on 2.0.2 and asap if someone shows me the way how 
to compile the latest version, I'll give try.
