Why did that make a difference?
Well, of course I would change only "smtp-amavis_recipient_limit",
but the difference is that otherwise the default limit delivers at
most 50 recipients at a time to the content filter. This reduces
opportunities for duplicate elimination (across lists), especially
with the default "enable_original_recipient = yes".
I've always (since ~2001) used large recipient limits with filter
transports, this also improves efficiency, no need to scan the same
content multiple times.
Hi Viktor,
Thanks for the reply! I've been on vacation so catching up on email. It
sounds like the better solution then is to add:
-o default_destination_recipient_limit=50000000
to the content filter definitions? ;)
