Dear list, I'm facing a problem where I have to adapt and optimize my smtp servers to a host's constraints which are as follow :
- maximum 3 connections to each MX of the host (he has 10 MX so potentially I should be able to make 30 connections) - maximum 1000 connections per MX per hour - maximum 100 emails sent per connection Today I'm using a special transport to match the host's domains and I limited the transport to 3 smtp processes so I don't break the first rule and get blocked. In order to catch and balance between the 10 MX, I also use smtp_mx_address_limit = 10 instead of the default 5. My problem is that this setup is far from optimal compared to the limitations and it slows down a lot my email delivery rate to these domains. Anyone have any tips on how I could do this better please ? Thanks a lot, Regards.
