I have a strange issue.
In the past years/month I got successfully mails from my OMV system.
But in the last couple of weeks sometimes my males got lost.
it COULD be in conjunction with updating to OMV 4 and Debian 9.
I am using a dedicated gmail account for sending the mails from my server. (DEDICATED@gmail.com)
The mail are send to a paid mail server (PRIVATE@example.com), wich again forwards them to another gmail account.
After some test I thing I can reproduce the issue.
This works
echo $(date); echo -en "From: \"Test\" <DEDICATED@gmail.com>\nSubject: Testmail\n$(date)" | /usr/sbin/sendmail PRIVATE@example.com
This does not work:
echo $(date); echo -en "From: \"Test\" <DEDICATED@gmail.com>\nSubject: Testmail\n$(date)" | /usr/sbin/sendmail root

When I log into DEDICATED@gmail.com I can see all mails in the send folder.
Even the ones that don't got forwarded.
When inspecting the "original message" (source code) of the mails in GMail I can see no difference between the ones that get send to PRIVATE@example.com and the ones that don't, except from timestamps and message-IDs.
My `/etc/postfix/recipient_canonical` looks like this
`/etc/aliases`
Another strange thing, the "to" is empty and only "bcc" is filled in the mails.
Is this expected?

Any idea what the cause of this issue could be?
