I want to authenticate one specific user for SMTP email sending (basic authentication).
- I created the user in local database (management/users)
- I configured Users authentication in the domain settings
- I enabled "allow users to use SMTP authentication" in the Outgoing relay setting of the domain.
But it doesn't work, I get the following error:
Code: Select all
Incoming MTA stage: 2015-08-06 12:30:14 fixed_login authenticator failed for xxxxxx.xxxx.xxxx [192.168.xxx.xxx]: 535 Incorrect authentication data (email@example.com)
What am I missing ?
