Re: TLS 1.0 1.1 not wirking

Should be configurable in main.cf. I just checked my config, it is not blocked in my config but I have no TLS 1.1 connections either.

Re: Next Major Release OS Version Survey 2020

I vote Rocky Linux or Debian

Rocky would be a simple transition, Debian not so much, but I do love Debian.

I don't really consider ubuntu or Devuan viable candidates.

Re: efa blocks acknowledgment of reading from the mailjet tool

Web bug / Web Beacon / Mail bug's (whatever you wqant to call them) are defused in eFa. you will need to make an exception for your mailjet

You'll need to use the "ignored web bug filenames" to bypass this in mailscanner

Re: Use multiple recipient delimiters

If that is not the problem then post the log, maybe "propagate_unmatched_extensions" is messing you up? (if its even configured) (I don't have eFa in front of me to investigate myself)

Re: Use multiple recipient delimiters

Why are you messing with the recipient delimiter at the spam gateway level? That sounds like a job for the Mail Server, the spam gateway should just be passing it on as it is.
