Yay! :-)

The sad bit is that if/when my old Mailman service gets rolled into the 
University's main mailing lists service, they run Majordomo (no, I'm not 
kidding, nor about them running Majorcool either!).

So if/when that happens, I'll have to move the ZendTo list elsewhere. 
I've got the other half of a physical server (It runs 2 VMs for me) in 
Ireland that can do it. I haven't used that half since the MailScanner 
list got moved off it, so there'll be some rust removal to do first.

Thanks for the warning.
