Please provide quantitative evidence that connection reuse is
necessary to get mail into the 'big providers' (i.e. they punish
connection rate and message rate differently).
Hi Wietse,
The biggest email service provider in France : Orange/Wanadoo.
We needed to disable TLS to reuse connections :
postconf -P "orange/unix/smtp_tls_security_level=none"
Here are their rules, got from ab...@orange.fr and confirmed by our logs :
- Maximum 1000 connections per hour
- Maximum 100 emails by connection
- Maximum 3 simultaneous connections
Yes and as they count connection at the IP level and have two domains
behind the same MX, you should reduce the
transport_destination_concurrency_limit to 1 to not exceed the 3
simultaneous connections limit. (you could theoretically reach 6 with
local transport trick because the single MX for these domains has two IP
address...)
