I am trying to let one or two outlook mail clients from the Internet use Astaro 5.006 as the proxy to an internal exchange server to SEND e-mail. In the past, I was able to accomplish this in Astaro 4.21 by configuring Astaro's "Outgoing Mail" settings as follows:
1) Create local user in Astaro with the same username/pw credentials as in MS Exchange.
2) "Allowed Networks" to "Empty List"
3) Specify the MS-Exchange server's IP as the smart host.
4) Turning on "TLS" and "SMTP Authentication"
5) Adding the local user created in step 1 to"Authentication Methods"
6) Configure outlook client to authenticate with the username/pw created in step 1
This worked just fine in 4.21 but no longer works in 5.00X. I get the error message in the log that says relaying is not allowed, despite authorizing that user to SMTP.
Any insight on what I'm doing wrong or why this doesn't work would be welcome.
Thanks!
