sender_dependent_relayhost_maps with different credentials for same relayhost

Hi,

i have:
sender_dependent_relayhost_maps = hash:/etc/postfix/relayhost_maps
smtp_sasl_password_maps = hash:/etc/postfix/smtp_auth

more /etc/postfix/relayhost_maps
@mydomain.de [smtp.1und1.de]:587
@my2domain.de [smtp.1und1.de]:587

more /etc/postfix/smtp_auth
[smtp.1und1.de]:587 mydomain:mydomainpass

How can i specify different credentials for same relayhost?

mails from my2domain.de should be relayed through 1und1 but with its own
credentials.

Thank you.

Stefan

Stefan Bauer:
smtp_sender_dependent_authentication = yes

This will first index smtp_sasl_password_maps with the sender
address, then the host, then the next-hop domain (whatever that
happens to be).
