Gitlab5.0 does not send email

After Service gitlab restart is used to restart the service, the email will not be sent. Remember that everything is normal after gitlab5.0 is installed.

Sendmail has been installed in the system and functions properly.

Check production. log and find no email sending record.

Check the system again.
