OT: SMTP auth, 2FA, Outlook

Jozsef Kadlecsik
Hi,

Is there a way to setup 2FA in SMTP auth (with postfix) when the client is
Outlook? It seems it does not support either GSSAPI (Kerberos) or client
cert auth.

Is there any way to get a working 2FA with Outlook in a non MS
environment?

Thanks any tips!

Best regards,
Jozsef

The answer is that depends on the SASL backend (Dovecot or Cyrus
SASL library), because Postfix does not implement SASL itself. It
just passes around the SASL server's challenges and the remote
client's responses.
