Unfortunately the best way to do multifactor authentication today is to use OAUTH2, which isn't currently supported for own installations. Or you can use client certs.
If you want to use some kind of MFA with tokens, you end up having to feed your token all the time. So the best option, for now, is device passwords.

weekforce policy server with 2fa, that just update allow_nets in dovecot user dict table, so all dovecot do is to check allow nets pr user from dict, i dont know if that is possible so imap / pop3 / lmtp and other service in dovecot dont need to mess with oauth2 or other complicated login system not supported everywhere
hope to see more stable security in dovecot with this, and certenly hope weekforce is not the only opensoure solution that is half dokumented :/
currently i just use ip2location in shorewall with asn numbers where i have known custommers, i got tired of blacklist random ips, bad idea hackers just could use another ip for free
no more fails here, it just remain to update microsoft servers with use port 465, 587, 993 without know passwords, who did dokument that ports is password less, shame on them
