This is the Debian postfix-gld package, which contains the gld program.

gld was written by Salim Gasmi <salim@gasmi.net>

This package was first put together by Santiago Vila <sanvila@debian.org>,
who currently maintains it.

The source for this release was downloaded from:

http://www.gasmi.net/down/gld-1.7.tgz

A small modification has been made to server.c so that it does
s/\+.*@/@/ on the sender, to deal with some VERP addresses used by some
mailing list managers.
