Forwarding mail from a custom domain using postfix fail with outlook
Okay so where to start....
I configured postfix on my debian server to forward mail sent to *@lafrappe.co to a gmail address and it’s working !! yay !
But.... it seems that every classic mail service can send mail (google, yahoo, etc) except outlook… every time I send an email from an outlook address to firstname.lastname@example.org for example I get a 550-5.7.1 error in outlook…
Some details, I’m using cloud flare so I had to do a wonky thing in it to forward properly my mail, but I don’t think that’s the reason for outlook failing to send a simple mail....
Why something so simple can be complicated like this.......
After two days searching around for an answer I think here is the place to find answers… I hope.
