Refesh O365 token when MFA is enabled #83

Closed backloop-biz closed 1 month ago

backloop-biz commented 3 months ago

Hello, I'm using this plugin on my postfix relay but unfortunately when the session of the user that authorize the app expire the mail flow is stopped with this error:

Presented multi-factor authentication has expired due to policies configured by your administrator, you must refresh your multi-factor authentication to acces

I solve by re-auth manually but is there a way to avoid this and not block the relay every time the token/session expire?

Yeah I don't know that there are great ways to address this (example). As far as I can tell (and I'm not very familiar with Azure) this is a restriction configured by the domain (tenant?) administrator and there's not much sasl-xoauth2 can do about it.
