[Mailman-Developers] Mailman 3 and LTMP

[Ian Eiloart]

Hi,

William's internship has finished here, so I think I'd better pick up this 
thread - if that's OK with you, William. I'll mail you off list about your 
two questions.


I've added a note to the docs about Exim's callout features. They allow 
Exim to determine not only whether the list exists, but whether the list 
will accept mail from the current sender - before accepting the message for 
delivery. I'll fill in the details later.
