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.

Update lists visually separated in the automated process. Hopefully this will make the update notices more readable.

Hi,
I'm still having troubles getting the nightly update script to actually UPDATE freshmeat using the 3.0 API. The home page always has the updates though. Hopefully I will have this resolved soon...

DynaStop updates
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.
