Description
Orange, a mainstream french ISP, and a few others, have a rate limit : without a slow transport, I get deferred messages with this : "Too many connections, slow down." It is a known issue https://blog.network-studio.fr/2011/06/30/too-many-connections-slow-down/
I managed to get it done with the overrides/ files :
overrides/postfix.cf :
transport_maps = socketmap:unix:/tmp/podop.socket:transport lmdb:/etc/postfix/transport.map
slow_destination_concurrency_limit = 1
slow_destination_recipient_limit = 20
slow_destination_rate_delay = 5s
slow_destination_concurrency_failed_cohort_limit=10
overrides/postfix.master :
slow/unix= slow unix - - n - 5 smtp -o syslog_name=postfix-slow
overrides/transport.map :
wanadoo.com slow:
wanadoo.fr slow:
orange.com slow:
orange.fr slow:
laposte.net slow:
free.fr slow:
hotmail.fr slow:
outlook.fr slow:
yahoo.fr slow:
I did not have time to fully test it, but it seems to work. Configuration values may need a fine tuning...
It would be nice to have such "slow" transport built in in Mailu, with an override possibility to edit the domain list.
