I have tried everything (I guess), such as writing my sasl_passwd and editing main.cf in the /etc/postfix folder (as described in 1). I also copied my LaunchDaemon plist with a different name to my /Library/LaunchDaemons folder (as described in 2).

While those people managed to get postfix to send smtp Gmail messages from their terminal under Mojave and El Capitan, respectively. I haven't managed to get their solutions to work under Catalina.

Any suggestions?


Take a look at https://gist.github.com/loziju/66d3f024e102704ff5222e54a4bfd50e Some people stated it works for them.

  • @SteveChambers thank you for your opinion. All the information is consolidated and summarized there. That's why I provided the link. If you have a better solution (answer to the question) I would be thankful to you and glad to see it. It is always easier to criticize than to create (c)

  • @SteveChambers is correct and it's not a criticism. Links can and often go stale so if/when it does, this answer becomes useless. The idea is to put the relevant point here so the user isn't required to leave this site to find the info.

  • No worries @iamtodor you don’t have to add more details. Anyone here can edit to summarize. No worries if a few downvotes rack up. After edits this could be the start of an amazing answer
