I tried with SparkPost but for obvious reasons the “impersonation” of the domain is restricted and therefore the mails do not arrive.
So I’m back to square one with the local SMTP. The local SMTP (PostFix) works with a sender_access
file with the address or domains allowed. So mine is there, the server is working (tried by hand and is being used by other tools) but no mather how much I put DISCOURSE_SMTP_AUTHENTICATION: none
I will always get SMTP-AUTH requested but missing user name
Is Discourse always trying to do SMTP-AUTH? Because the server does not have auth in any way, re-checked.
Right now I’m at bare minimum like mentioned here:
DISCOURSE_SMTP_ADDRESS: IP_ADDRESS
DISCOURSE_SMTP_PORT: 25
DISCOURSE_SMTP_AUTHENTICATION:NONE
DISCOURSE_SMTP_ENABLE_START_TLS: false
But still, no success.
PD: May I add, after both @pfaffman and @jayqueue2 suggestions I did tried SparkPost but only to be faced by Corporate Blockades It connected on the first try and worked like a charm, however.
