[PLUG] Re: [lug] Spam Filtering With Remote Access

[John Sechrest]

We are running Cyrus at PEAK. 

It does some things nicely.

However, it has broken all of the procmail and .forward 
based mail filtering. And so has broken many people.


I have chosen to take spam instead of moving to cyrus personally
because I process on the order of 4000 messages a day. And
with Cyrus breaking all the tools that I currently use, I would
not be able to function.

Cyrus uses a specific structure for message storage. And
as such, samba would not work underneath it.


I would leave an escape for the onid users who try to filter
mail. Loosing procmail is a big loss. The cyrus filter tools
are not nearly as flexible nor as powerful.
