Hi,
Trying to deal with a destination server that is really picky about the speed I deliver messages to it. In a setting like transport_destination_concurrency_limit what does destination means exactly? My doubt exists because I have more than one email address destination domain that have the same MX records. As the destination server apparently controls the rate of deliver per origin server IP address I have to know if, for example, I have 2 email address destination domains, example1.org and example2.org both with the same MX records: let's say mail.example.org when I set: smtp_destination_concurrency_limit = 2 what will happen if I send several emails for both email address destination domains at the same time? Will I have 2 simultaneous connections to mail.example.org or 4? The destination in smtp_destination_concurrency_limit here is the MX final domain or my email adresses destination domains (example1.org and example2.org in this example)? Regards, Rodrigo Severo
