I am unsure if this post belongs here or on Server Fault as I cannot say for sure if this is a Magento 2 issue or a Postfix issue.

Environment Magento 2.1.2 Postfix 2.11.0 Ubuntu 14.04.5 LTS Trusty Tahr

First to skip the obvious questions: Magento 2 configuration checks:

  1. Stores --> Configuration --> Sales --> Sales Emails --> All are enabled (Not that it matters as I am clicking on the send button of an existing order)
  2. Stores --> Configuration --> Advanced --> System --> Mail Sending Settings --> Disable Email Communications = No

To ensure that Magento is providing the correct details I added some logging statements into {magento_root}/vendor/magento/framework/Mail/Transport.php to spit out the contents of \Magento\Framework\Mail\MessageInterface $message and confirmed that the "To" value in the headers, the "to" and the "recipient" address were all correct.

Postfix settings: main.cf

Now the output I'm seeing in /var/log/mail.log is:

May 10 16:23:01 mydomain postfix/pickup[11549]: 4D66124427: uid=1000 from=<bitnami>

May 10 16:23:05 mydomain postfix/smtp[11582]: 4D66124427: to=<[email protected]>, orig_to=<adminuser>, relay=smtp.office365.com[40.101.72.226]:587, delay=4.6, delays=0.02/0/4.2/0.37, dsn=2.6.0, status=sent (250 2.6.0 <20170510162301.$
May 10 16:23:05 mydomain postfix/qmgr[11550]: 4D66124427: removed

The to= is the admin username appended to the domain name and not the customers email in Magento.

The reason I am not sure if this is a Magento or Postfix issue is because sending a test email with:

echo "Test Message" | mail -s "Test Subject" [email protected]

works fine!

Anyone have any ideas?

the "removed" means removed from the queue, not removed from your mailbox.

Does > sudo postqueue -p display anything interesting?

  • Just the above email that appears periodically on a retry doomed to failure. I also tried: sudo postsuper -d deferred to remove any potential items holding up the queue. Repeated email send from Magento above, same hting happens

  • Have also emptied the admin users mail box in postfix for good measure
