From Claus Assmann:
Here's the latest status update: For various reasons, the software has been renamed to MeTA1. The mailing lists will be renamed accordingly: domain: sendmailx.org -> MeTA1.org localparts: smx-developers -> MeTA1-developers smx-design -> MeTA1-design For now, I just copy all addresses from the old lists to the new list. If you don't want to participate any longer, please contact me directly. As you probably noticed, I took some time off from working on the MTA (only fixing bugs if a problem showed up), but now I'm back and one of my current projects is to look into integrating Arena as scripting language (see some earlier mails about this topic). I will send out some more information "soon" on the new list, hopefully you will adjust your filters by then.
More information about MeTA1 and the Arena scripting language.
