Don't use this daemon for new installations, it's deprecated in favour of tac_plus-ng.
A tarball is available from GitHub. The historic snapshot archive is gone for good.
Sending a mail via the Event-Driven Servers Google group might be an option too, but the mailing system there seems to have reliability issues. That group is moderated, first-time posters will need my approval. Don't send your mail more than once (I have absolutely no trouble with approving re-sends, so just don't do it). Your mail will show up, most certainly, sooner or later.
This is a non-commercial project. There is no private support. At all. Theres no paid-for support, either. I'm happy to support you in public, if I have spare time for that. Support requests or inquries sent to any of my private email addresses will be silently discarded by a mail filter. Use the public channels, please.
Cheers,
Marc
