Thanks, this (and previous portions) is helpful. I think I have everything
I
need now. Regarding batching messages by type, would it make sense
to simply have a transport defined for each specific type, and then max_rcpt
would not need to be pinned down? The transport could provide the login
info as you suggested, and the auth happens once per batch of messages,
all of the same type.
