Thanks for feedback
Then i am back to square one!
We need the server to work with SMTP Authentication so its only used by authorized users.
I re-ran the squirrelmail and ispconfig install scripts but that did not help
I still cant get it to work with SMTP Authentication.
It asks me to enter the user and pass (fullmail address/password) but after 5sec it asks again and it does not do anything. Same username and password works in squirrelmail so i know its the right one.
If i send from localdomain to another domain on same server it works from outlook without smtp authetication as it is supposed to.
If I send out from our server it does not work.
I have no idea how to get around it
I have read that it does not work out of the box with Ubuntu 11.10 and we need to downgrade some packets to 11.04. Others say that I just have to do some changes to the smtp.conf file.
Is there anymore trouble shooting anyone can advice me to do?
If not I am really considering installing Debian/ISPConfig as not sure how to mvoe forward from here
