When osticket 1.17 sends email alerts/notification i get this BAD HEADER ERROR:
X-Amavis-Alert: BAD HEADER SECTION, Duplicate header field: "Date"
It passes on our internal server but i see that Gmail is blocking email due to this error:
Message ID '[unknown:7573DC0CEA:mail]'
osticket@progermail.com -->

i tested sending an email from our osticket mail server (zimbra) and passes without problem, so it's an issue with osticket 1.17
