You can easily install this filter on your own Post.Office server. However you need to save the HTML source to your harddrive and change 1 line in the HTML source.

Entering this filter manually into Post.Office will take quite some time as you have to enter each line separately and then go back to the SMTP filter interface, enter the next line, etc. Using this page, you can install the filter in one go.

Attention: Installing this filter will slow down Post.Office significantly. When I installed it on our Post.Office server (PowerMac G4 Dual 1.25 GHz, 1 GB RAM), each message was delayed by 6 seconds as this filter was being processed. This even happened when the filter was disabled (unchecking "Discard" and "Copy To"). Once I deleted the filter again, the messages were processed much faster!

In order to use this filter, you should

log in to your Post.Office web interface using the postmaster account
go to System Config -> Configure An SMTP Filter
copy the unique identifier string from the browser location line, e.g.
http://www.mydomain.com:9090/9ae594844afcaefe1ff8fa9c4a061da0/SMTPFilters
paste the identifier string into the "base href" tag of this page
change the www.mydomain.com:9090 to your server
run this page from your local browser

<BASE HREF="http://<HOSTNAME>:<PORT>/<UNIQUE_IDENTIFIER>/">
