A transport map looks something like this:

server.tld            smtp:[upstream.mail.exchange]
.server.other.tld     smtp:[other.mail.exchange]

What you are referring to is the ability to have something like this in
the sasl_passwd file:

upstream.mail.exchange                user@some.isp.tld:password
other.mail.exchange                   user@other.isp.tld:password

Where a different username/password is used for different mail servers.
