Hello,
The link:
http://braindamage.alal.com/software/nspam.html
On page:
https://openacs.org/doc/openacs-5-2/individual-programs.html
appears to be dead.
Sourceforge appears to have a rather exhaustive collection of source for aolserver:
http://sourceforge.net/project/showfiles.php?group_id=3152
unfortunately, ns_pam is not among them. I have the source for ns_pam and would be more than happy to pass it along to the powers that be so it can get loaded on sourceforge and have the link fixed.
