I have a situation where I need to use different relay logins to the
same host depending on the local sender. For example:
If the local user is [email protected] the the relay host login
needs to be [email protected].
However, if the local user is [email protected] then the relay host
login needs to be [email protected].
It seems that relay_sender only maps to one login:
[email protected] [smtp.relay.com]:587
[email protected] [smtp.relay.com]:587
And of course in sasl_password:
[smtp.relay.com]:587 uuuuuu:keystring
[smtp.relay.com]:587 xxxx:anotherkeystring
Is there not a way to distinguish which login to use in this case? If
so, how? TIA

Hi Dennis
I saw a section here on how to configure a sender dependent SASL
authentication:
https://www.postfix.org/SASL_README.html
using smtp_sender_dependent_authentication
