hi
we have here a special mail delivery problem
our mail server (Postfix.20010228 on Mandrake 8.0) is running fine under normal conditions (about 1000 messages a day)
but we need to make a bulk send of 15000 emails every 3 months
no spam, it's a bulletin for our customers
we do this in three attempts of 5000 mails
the mails are prepared using a custom program and then send at once (using ms outlook)
and now the problem - the delivery is after sending about 200 mails or imediately after pushing the send button very slow, it takes about 30 or more seconds for one mail to be taken from the outbox queue - so it takes days to perform this task
what could be the problem - slow internet connection (64kbit), full active or defered queue?
i found out, that about 25% of the messages are being defered
i was looking for configuration settings that could make the delivery faster but i can't figure out which one will solve the problem
i thought these could be usefull
qmgr_message_active_limit
queue_minfree
default_destination_concurency_limit
hash_queue_depth
maximal or minimal_backoff_time
queue_run_delay
fast_flush_* settings
or even
ignore_mx_lookup_error
smtp_skip_4xx_greeting
smtp_skip_5xx_greeting
to reduce the deferals
could some of them be useful for me?
do you think the problem is on postfix, if so how to solve it, or could it be slowed somewhere else?
thanx
