Thanks for the reply.
Yes, I need smtp_sender_dependent_authentication because the upstream
ISP will only accept incoming mails from the authenticated user.
The feature you suggest may not work on my scenario, because if I send
email from user1 but authenticating with user2 (the default user), my
ISP may reject that mail.

Hi,
I've set up sieve vacation reply but my postfix setup is using
smtp_sasl_password_maps and smtp_sender_dependent_authentication.
The problem is that Sieve will send the reply with "from=<>" to prevent
bounces.
This means that Postfix has no way to authenticate to my ISP because it
doesn't find the sender entry on the sasl DB.
How can I use both features toghether?
Apparently, there is no empty_address_xxx_lookup_key feature for
xxx in smtp_sender_dependent_authentication or smtp_sasl_password_maps.
Do you really need smtp_sender_dependent_authentication?
