Suddenly, I started getting this error messages:

 

Your message to the following recipients cannot be delivered

 

<aaa@...>

<<<550 User <#> unknown

 

However the message is delivered successfully, but this error message arrives in a separate mail. What could be the problem?

Send the full error email that you receive, with all of its headers.  Also include the mail logs.  Find the error in your log file, then look for all of the lines with the same message ID.
