The domain name is owned by someone else now and the old site doesn't appear to be archived at archive.org.

According to ​https://mediawiki.gnustep.org/index.php/Pantomime the current version is 1.4.0 and Riccardo Mottola, who has also contributed to MacPorts, is an upstream maintainer. The project's homepage is supposed to be ​http://www.nongnu.org/gnustep-nonfsf/gnumail/ now but that server does not respond for me now, though it is archived at archive.org. Maybe we should update the port. Riccardo, do you want to do that?
