well, right, like I said, this is from a mailman mailing list , and
there are 3 remote recipients in the list. But in the real list I want
to implement, there are hundreds at various addresses and I would like
to throttle ALL outgoing deliveries if I can. I guess best case scenario
now is to serialize the delivery process somehow.
Postfix will send 50 recipients at a time by default. Does the ISP
mandate a lower number of recipients per message? Sending more messages
with fewer recipients each is certainly not helpful to the ISP. Whatever
you set the smtp_destination_recipient_limit to, don't make it 1.
If you really want to get one recipient per message, consider using VERP,
a good idea with lists anyway.
I looked it up and here is the real scoop.. ;)
*You may not include more than 100 recipients in a single email. Messages will
not
be sent to any recipients in excess of 100.
*You may not exceed 500 recipients in 1 hour. Exceeding 500 recipients in 1 hour
will result in the suspension of your ability to send email for 24 hours.
so If I use the following:
smtp_destination_recipient_limit = 8
smtp_destination_rate_delay = 60
this means that only 480 messages will get relayed in one hour, right?
thanks/regards,
Jason
