I am fine with the end result. The untrusted message is rather cosmetic, i would like to know how to import the certificate or rather trust the server (as i thought the mynetwork variable would do), but it's no biggie.
The server is inside our lan and the relay will only be used for our helpdesk, which will be internal. Some would argue that using the virtual smtp server (that asks for no password) is better, since with the current setup i have to make sure the user that will send the mail (which should be static, as they will be automatically sent by the helpdesk) has a password that either doesn't change or keep the password updated in the hash. -- View this message in context: http://postfix.1071664.n5.nabble.com/Exchange-2007-gives-535-5-7-3-Authentication-unsuccessful-tp65072p65129.html Sent from the Postfix Users mailing list archive at Nabble.com.
