/etc/postfix/main.cf
slow_destination_concurrency_limit = 30 slow_destination_rate_delay = 120s
/var/spool/postfix/plesk/transport
[ICODE]orange.fr slow:
wanadoo.fr slow:
laposte.net slow:
outlook.com slow:
hotmail.fr slow:
gmail.com slow:

windowslive.com slow:
hotmail.com slow:
icloud.com slow:
outlook.fr slow:
msn.com slow:

Hello,
Yes we found the solution here

You need to add this in master.cf
# # Slow # slow unix - - n - 5 smtp -o syslog_name=postfix-slow -o smtp_destination_concurrency_limit=3 -o slow_destination_rate_delay=1

This must be added in main.cf
transport_maps = hash:/var/spool/postfix/plesk/transport slow_destination_recipient_limit = 30 slow_destination_concurrency_limit = 2 slow_destination_rate_delay = 60s default_destination_concurrency_limit = 10

And in /var/spool/postfix/plesk/transport
orange.fr slow: wanadoo.fr slow: laposte.net slow: outlook.com slow: hotmail.fr slow: gmail.com slow: bluewin.ch slow: windowslive.com slow: hotmail.com slow: icloud.com slow: outlook.fr slow: msn.com slow: ne.ch slow:

Hope that can help.
