Really the OP is lost on how this works and I have given way too much information on how to make Postfix use say admin as who is using the email john@company.com. Works the same way as Netbios names to route for the associated IP.
IanMosley is closer, but... when i firstly started Outlook 2019, it begins with some configuration wizard and didn't allow me to do anything else. See first screenshot - it is one part of this.
And that is the problem - it allows set only email address, not username. This configuration wizard is unusable for me and without finishing it, Outlook 2019 did not continue further.
Yes, i already got it. I can use virtual users and maintain another database (or table in textfile) of this alternative usernames (in other word aliases) for my MTA. Fine, but i really don't want to do it just because only one MUA from many needs it.
If only one application need something unusual without really good reason i must consider it error. Ok?
But fortunatelly, there is way around.
As i linked before, i can run Outlook 2019 with parameter "outlook.exe /manageprofiles". It will start similar dialog to one IanMosley uploaded.
It looks little retro, it is little chaotic, but it allows set everything i needs, especially username.
Thanks again, even if we did not understand each other exactly. Now, problem is solved.
Hi there @swec
Easier get around for others who have this problem with outlook
Just use the applet in the control panel -- it's labelled outlook 2016 (or mail 2016) - even for 2019. That will get you back into those old screens that allow manual config.
I do hate those wretched auto config wizards when they don't work or give you options you need but more and more email clients seem to be doing this now - including thunderbird.
Note - control panel still exists in W10 even in the latest insider builds.
Cheers
