They are, we probably have to limit the digest size on per list basis.
By default it should probably be the same as the max message size for the
list.

Yes, various monitoring lists usually have 3-5 subscribers and can receive
tons on mail in a matter of minutes thus stopping all other processing.
It's a rather common case for corp. lists.
Same goes to archiving (outgoing directory), but it's not as time sensitive
as the delivery to list subscribers.

Will try that, alhough it's kinda hard when you have a large number of lists
(I have about 3,200 now).

Sympa seems to be rather slow, it can only process about 2-3 msgs/sec tops
on my dual-CPU machine.
Same lists expanded thru aliases work much faster.
I understand sympa is doing various checks, but probably something can be
done to speed-up the processing.
Lots of sites can't afford several hours delay because of one list receiving
a large number of messages.
Any idea what part of code needs to be optimized ?
I'm still on 3.x though, so it may have changed in 4.x...

thanks
