PanAm Dynamic List

WARNING: Service Out Of Order
Article included for historical purposes only. [Template:Out_of_order]

quoted from thir website:"Update 08 MAR 2007: The Pan-Am Dynamic List project has outlived its usefulness and has been terminated. Some of you may have noticed that the listings were removed yesterday; this is an attempt to make sure your e-mail filters were cleared of PDL data automatically, but we will continue to maintain a "blank" database until the end of 2007 so you have a chance to remove the PDL from your mail systems.

If you have backups of this data, please do not use it for junk e-mail filtering as it will eventually fall out of date unmaintained.

In the PDL's place, please consider the Spamhaus Policy Block List (PBL) project. Its goals and charter are very similar to the PDL's:"

Originally one of the first 'Dial-up list' (DUL).

The creator allowed MAPS to use the list as the (once) famous MAPS-DUL as he got employed at MAPS.
But as he left MAPS they claimed the exclusive copyright, threathed with lawyers and the PDL had to be restarted from scratch.
