[sqwebmail] Change place of ~/.mailfilter -> ~/.mail/mailfilter

[Lilla]

Hi,

Is it possible to change the place of the ~user/.mailfilter file to e g 
~user/.mail/mailfilter without hacking the sourcecode? If not, how do I hack 
the sourcecode most easilly to enable ~user/.mail/mailfilter ?

Thanks a lot for any hint!
