Dovecot Submission Proxy Auth

[Jacky]

Hi,

Just found out that Postfix does not implement/support the AUTH=sender 
parameter.

So, back to Dovecot, can we use variables in the

submission_relay_user =
submission_relay_password =

then Dovecot will forward the username and password information of the 
current user to the Postfix submission service for authentication?

Best regards,

Jacky
