Hi, here is my problem:
Sending mail via applications (ex. Outlook, Thunderbird) works fine over my smtp server, using a TLS secured connection.
Now I like to use my smtp on the same server of the smtp itself, on a web application.
However, using the same smtp settings of in Outlook, when sending a test e-mail to an external domain, results in the error you can find below, namely 'Relay access denied'..
When I use as test recipient a local mailaddress, the message is succesfully sent..
Any idea what could be the problem here? Looks like sasl is not working on my localhost, causing the relay access denied? How can I fix this? Any hint is welcome. Thank you in advance
