Hello,

I'm trying to auth sasl using another smtp server's sasl auth.

scenario is as shown below:

[client] -> [postfix_as_email_gateway with auth plain] -> [another smtp server sasl auth plain enabled]

The closest you can likely come to this is to use Cyrus SASL with rimap authentication which will allow you to auth against an *IMAP* server (which can be remote).

postfix has no userdb & passdb. Is it possible that postfix connect to another smtp server and validate auth plain user credentials? Basically i want that postfix make auth against another server's smtp auth.

What is the right way to do this configuration?

Rethink your strategy. Perhaps connect Dovecot SASL directly to the remote database for auth?
