CE Service Desk - what happened with my emails

General
#1

Hello there!

I just install latest GitLab CE in virtual machine with Ubuntu Groovy Server.
I want to try to use Service Desk before I introduce it in my company.

I installed postfix and courier-imap and configured according to the documentation.

I can send and receive emails (via terminal)

pplaczek@u2010server2:~$ echo "This is not working again. Please help me." | mail -s "service-desk problem" gitlab+gitlab-instance-5fe145dd-monitoring-1-issue-@u2010server2

gitlab@u2010server2:~$ mail
"/home/gitlab/Maildir": 1 message 1 new
>N   1 pplaczek                        13/595   service-desk p
?

I also can get this message via IMAP:

placzek@u2010server2:~$ telnet localhost 143
Trying 127.0.0.1...
Connected to localhost.

And I can see that the GitLab doing something with this message, but I don’t know exactly what, and why it doesn’t create a new issue…
