I'm running Postfix 2.6 and using phplist to send a newsletter to about
200 members of my church. All the mail makes it from phplist into the
postfix queue on my local machine. From my local machine, I have to
relay all my mail via my ISP's server. I am able to send about 10
messages from my local queue to my ISP before I start seeing errors in
my maillog:
status=deferred (delivery temporarily suspended: lost connection
On the next queue run, another 10 messages get through before my ISP
starts dropping connection again. I called my ISP and it said that as
long as I sent in batches of 100 or less, there were no restrictions.
I checked man 5 postconf and see options such as
default_destination_recipient_limit, default_destination_rate_delay, and
default_destination_concurrency_limit. All the defaults seem like they
would be below my ISPs limit of 100 but I don't really understand them.
I've played with the options but still have trouble.
Would someone please explain them to me or kick me to a link that will?
My head is just too thick. :)
Thanks,
Drew
