DynaStop is a utility to examine IPv4 based addresses for Exim and procmail for the purpose of filtering based upon patterns defined by the administrator. This can be a pivotal factor in email filtering and server load management, since dynamic IP addresses are typically used for dial-up, DHCP, and DSL accounts. All of which have a designated mail exchange server through which all outbound mail flows as defined with many, if not most, large Internet service providers.

Hello,
I will now be updating DynaStop's config files on a daily basis. DynaStop has proven stable enough so that it has become a critical part of many systems and as such, updates are now critical.
Using subject filtering with ProcMail
Hello,
Here is a recipe that will work well with procmail:
RCPTDomain=`formail -uTo: | formail -xTo: | cut -d@ -f2`
RCPTSub=`formail -uSubject: | formail -xSubject:`
:0fw
| /usr/exim/DynaStop 127.0.0.1 stdin $RCPTdomain $RCPTSub
:0
* ^X-DynaStop:.*D[1-3]
Spam
With this recipe at the top of your procmail rc file, Procmail will take advantage of the new Subject filtering feature.
Subject filter usage
Here is a post on my DynaStop forum that demonstrates how to use this filtering method.
