[c-nsp] OT: Best Online Antispam Service

[Maxwell Reid]

Our experience with Postini was pretty good until Google bought them  
out.  When that happened some of postini's 'quirks' became more  
apparent (black holed mails) and the service sorta went down hill from  
there.


I'd recommend using a provider more *focused* on email that hasn't  
been bought out by a giant advertising firm or getting an appliance /  
rolling your own system.

I'd point out that Postini et. al. don't really save you that much in  
terms of bandwidth.  They aren't generally setup as store and forward  
services,  they operate by opening  a backend proxy connection to your  
mail server anyway, so you'll see header traffic, and most spam is  
relatively small fry byte wise.  If you're starving bandwidth wise,  
traffic shaping and ratelimiting are better options.

Also, if you're an ISP, they won't solve the problem of outbound  
scanning; that only applies to Enterprises.
