I have ZCS 7.1.4 installed and one account registered there. Using web client. Though preferences I've added one more account, which is on google.
When I try to send mail from google account ( change From header to google account ), mail is sent. But on remote side it is classified as spam. Under remote sides I understand gmail, other companies using spam assassin.
I guess issue is in mail headers. They are like the following:
Sender: ZIMBRA_ACCOUNT ( ???? )
I guess issue here is that sender is set to something different than correspondence should be.
Any ideas why this could happen?
