First of all, sorry if this post is not allowed, it is somewhat relevant to Surgemail but not directly involved with it.

What are others doing for spam and virus filtering solutions before the email hits your Surgemail server?  I am looking at possibly replacing my Barracuda Spam and Virus email gateway with a hosted solution but would like to get reviews from others who have tried and liked/disliked.

Cost is a consideration as the virus/spam scanning as it is a value added service, I have calculated out our costs to be roughly $0.20 per sub (CDN pricing), I would like to try to keep my numbers in that range if possible.  I have seen other services out there that offer all these great bells and whistles, offer protection for Office 365, Google Apps, etc, that is overkill or way to the left of what I need.

I would like a simple service that allows clients to log in using their current username and password (IMAP or POP3 login back to surgemail) and be able to adjust and view their spam and virus’s that the system has quarantined. The system needs to support multiple domains with different users per domain.

Thanks,
