You pedant :-)
Granted although that raises the other issue... Barry mentioned
yesterday that he was putting the dropped SMTP_MAX_RCPTS functionality
back in... but I thought it had deliberately gone on the basis that
mailman was giving the mail delivery job to the MTA and not trying to
second guess it.
If we do split the list, then ideally it should be sorted.... at least
so identical domains go together and maybe more intelligently than
that.... and we're back to trying to second guess the MTA at its own

I guess that we need a per MTA tuning/configuration document. I pretty
much have that in the exim mailman howto (always willing to take
contributions/comments on that BTW - especially if they suggest
solutions rather than just raising criticisms). Have we got that data
for the other MTAs? Of course we could have comparisons of the
suitabilities of different MTAs if people enjoy a decent flamefest.
