[BlueOnyx:12402] Mail filtering alternative to Postini

[David Thacker]

Greetings all,

I've been offering Postini mail filtering service to many of my domain 
hosting customers for several years now. As you might know, Google bought 
Postini a few years back, and this year they are shutting down the Postini 
service and migrating customers to Google Apps.

My Postini service was obtained through a reseller, not through direct 
contracts with Postini, as this was the best option for the number of 
hosted accounts I have. This reseller is now offering to migrate their 
customers (including myself) to McAfee email security services, similar to 
what Postini was providing.

I am taking this transition as an opportunity to consider other email 
filtering options. I do like the "mail filtering as a service" model 
compared to running my own mail filtering appliance, and am not really 
interested in adding spam & AV filtering duties to my BX server. I'd 
rather offload that task.

Do any of you have any suggestions of mail filtering services to look at, 
or other alternatives I might not have considered? Have any of you gone 
through the same transition away from Postini, and if so, how has the 
replacement service been in comparison?

Thanks in advance,

David Thacker
