[nycbug-talk] Anti-spam services

[Francisco Reyes]

Anyone happily using an anti-spam, at the MX level, service?
Tried Postini and although their price is very reasonable, $3/year/per
user, their interface leaves much to be desired.

In particular I am looking for something simple enough that one could let a
non techie manage directly.

One  requirement is that it must support some form of Quarantine where the
users can check for valid messages and release them.
