Consider the following scenario:
When sending an email via Smartermail, the sender receives a 550 No such user here error.
If SMTP authentication is enabled on the Smartermail server, the sender’s email client needs to be configured to send the login/password information to the server so that the server can validate and authenticate the sender.
Consider the following scenario:
Plesk control panel installed on top of a hosted mail server.
Inside of Plesk, an email object is created and then enabled for a mail group. Email addresses (recipients) are added to the mail group.
An email is sent to the mail group and is never received by the recipients.
The email log file shows that the email was received successfully however it was never delivered on to the intended recipients (in the mail group).
Resolution:
The mail object in Plesk has the mail group and mailbox enabled. Because both are enabled the email is sent to the mailbox and the mail transaction is complete.
Once the mailbox was turned off in Plesk the email is properly sent to the intended recipients (in the mail group).

Make sure that the third party application is using a fully qualified SMTP address when attempting to send/relay through Smartermail.
Smartertools has shown me how to “disable” smmailfilter.exe from running inside of Plesk in Smartermail. Actually, it is not disabling it, so to say…but more of not have it run.
In Smartermail
Settings/General Settings
Spool Tab
If C:\Program Files (x86)\Parallels\Plesk\admin\bin\smmailfilter.exe %filepath is in the “command line file to run on new mail” is enabled, disable it.
However, this will disable all email functions inside of Plesk.
