Onsite Spam Filtering - any recommendations?
Recently, a few obviously spam emails are slipping through Exchange 2013's spam filtering despite me constantly adding bad words to the system!
I'd like to pop something simple in place - free/virtual machine hosted - that'll just stop the obvious drugstore/weightloss stuff from landing in inboxes.
I've come across both:
Xeams Home - A free email and spam filtering server with SMTP, POP3 and IMAP
I was thinking about keeping them behind the proxy and updating them manually as a little precaution but just wondered if anyone has had any experience with either or could recommend anything else!
