mkdir error in lint

[Mark Chaney]

 When run lint, im getting the following error:

Aug 16 21:47:16.112 [4457] dbg: config: mkdir /var/www/.spamassassin 
failed: mkdir /var/www/.spamassassin: Permission denied at 
/usr/share/perl5/Mail/SpamAssassin.pm line 1853

Though i have no idea what its for and why it would be trying to write 
to a www folder.

Thanks,
Mark
