I working with an application which collects data and emails me the
results. Reading it in a mailinglist-like fashion is optimal for me.
It can generate a large number of mails in a short time, so I'm trying
to limit how many concurrent sockets pf on that box opens with my MXs.
Each subset of messages has a different +extension in the localpart.
Ideally, I'd like it to open one to each of the equal-priority MXs,
starttls with each, and dump the mails between them until the queue
drains.
I tried setting:
smtp_destination_concurrency_limit = 2
smtp_connection_cache_destinations = jhcloos.com
but still get as many Verified TLS connection established messages in
the logs as status=sent lines.
And netstat agrees that many sockets are used in parallel.
Do any of:
smtp_dns_support_level=dnssec
smtp_use_tls=yes
smtp_enforce_tls=yes
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache
smtp_tls_security_level = dane
smtp_tls_note_starttls_offer = yes
interfere with concurrency limits?
That box has pf 2.11.1.
