If I submit a message with the following message-id to the postfix sendmail interface using */usr/sbin/sendmail -r...@here.com -t -oi -oem* Message-Id: *58faf4a4-8e6f-4b60-af87-173efa7d3...@here.com*
The Postfix sendmail interface receives the message with the specified message-id: Mar 9 03:49:05 howsmy postfix/cleanup[16499]: 3E8C66C12E7: message-id=* 58faf4a4-8e6f-4b60-af87-173efa7d3...@here.com* When the message arrives, it appears not to have a message-id at all, and the receiver generates one. Message-Id: <*4f597db2.e7b9ec0a.6395.ffff816dsmtpin_ad...@mx.google.com*> If I don't submit a message-id to postfix sendmail, the message-id generated by postfix arrives in the receiving SMTP server correctly as sent. If I try to specify the message-id, apparently nothing gets sent for a message-id field by postfix. What am I missing?
