Global internet providers aim is to provide access that is effortless to utilize. They provide access that is as fast as you absolutely need it to be, and will work with the system you have.

At first, thanks aslot for making this (almost) clear.

What I don’t understand is: If …
“[a] user1@isp1.com must be relay via smtp.isp1.com.
[b] user1@isp2.com must be relay via smtp.isp2.com.”
(so there is only user1 involved)

… then why is this line in /etc/postfix/passwd ?
“user1@isp2.com user2@isp2.com:password4isp2″

Where does user2 coming from all the sudden?!

Shouldn’t it be like this
“user1@isp2.com user1@isp2.com:password4isp2″

or do you just want to show, that the username on the “real” isp2.com has not necessarily to correspondent with the “local” user1?

Thanks for answering,
Coschuetzer
