[koby at mksoft.co.il]

 Hello Rspamd users ,
 As following this project for some time I found my self serching for
 info about this project all the time with any success until now at 
 list.

 I would like to find more info how can i block file base on 
 type/sender/reciever etc..
 I also like to find some example to use rspamd as a *mail gateway** 
 (postfix if I may) and not as a local mail server.

 Can some one plesea help

 Thank you all for your co operation
