BioMail (new link) was apparently shut down by its author's department, according to the message posted at its former site. Dmitry also stated, in a message to all users, "I have yet to find a host where I can continue the BioMail alert service temporarily or permanently. If someone can help, I would be very glad. BioMail requires a Unix system with Perl, a webserver installed, and a stable internet connection (Linux computer with Apache is preferable)." Can anyone lend a few server processes to get this up and running asap? [update (3/3)]: Dmitry just let me know via email that not only has the sourceforge crew ok'd running the server there, but he also already received two messages from some of you friendly folks who saw this or got the message from oss4lib-list. Way to go, folks... :)
