Mail undeliverable to Virtualmin users


Something bad is happening. Emails inbound are being bounced back to senders with messages like this:

The full error report contained in the bounced email:

Reporting-MTA: dns; X-Postfix-Queue-ID: A2312A8FD X-Postfix-Sender: rfc822; Arrival-Date: Wed, 24 Jun 2015 00:25:20 +0000 (UTC)

Final-Recipient: rfc822;firstname.the-domaint@com Original-Recipient: rfc822; Action: failed Status: 5.4.4 Diagnostic-Code: X-Postfix; Host or domain name not found. Name service error for name=com type=A: Host found but no data record of requested type

Please notice the expansion and the solitary "name=com" on the last line of the error report

Why are email address:

1) concatenated to contain a period mark "." between name and domain, and;

2) I'm really confused as to why Virtualmin or postfix is trying to lookup "com".

Thank you.
