Hello,

is it possible based on the information we get from the IMAP ID fields sent by a client to start some actions e.g. reject an IMAP client with a certain OS version?

Hi!

Dovecot auth policy feature allows you to inspect IMAP ID fields, if they are sent pre-login. You can use something like weakforced for this.

See https://doc.dovecot.org/configuration_manual/authentication/auth_policy/#aut...
