tls_verify_mode — determine whether a TLS certificate is required
TLS_Verify_Mode = "none|require"
This option determines whether a TLS certificate is required for inbound mail, if TLS is started. It is not a means for requiring TLS .
Momentum does have an authentication hook (core_validate_auth_hook) for Lua and Sieve scripts to handle authentication results. Additionally, if the connection has been upgraded to TLS, the vctx will contain the key
tls with a value of
on. Using these two methods, you should be able to require successful authentication and a TLS connection.
This option can be set to the following:
none– No client certificate is required, and any certificate presented is ignored. If an invalid certificate is presented, no action is taken.
require– A client certificate is required, and it will be verified. If an invalid certificate is presented, the policy scripts determine the action taken.
not specified – A client certificate is optional, and any certificate presented will be verifed. However, there is no built-in action based on whether the certificate passes or fails verification. The policy scripts determine the action taken.
By default, this option is not specified.
tls_verify_mode is valid in the listener, listen, peer and pathway scopes.
