Subject: reportbug can't deliver message since the mail server reports relay not permitted

package: reportbug
version: 6.6.3+devuan1.3 

I tried to report a bug and when reportbug tries to deliver to "Report
will be sent to "Devuan Bug Tracking System" <[email-masked]>"
 the result is: "SMTP send failure: [email-masked]': (550,
 'relay not permitted')}. Do you want to retry (or else save the report
 and exit)? [Y|n|q|?]? ?"
