Re: Questions regarding features in Zimbra free and NE

Dear,
According to https://www.zimbra.com/email-server-sof ... omparison/ , you must use NE for those features.
In case of using OSE, there are some alternatives such as OPENPGP Zimlet, 2fa ZIMLET for OSE.
Best regards,

Re: Email Zimbra Considered as Spam Box Gmail/yahoo

This is normal behavior of gmail and outlook.com when you use new domain and IP. You have to warm up your ip and domain.It will take about 2-3 weeks. Gmail users need to reply your emails, mark them not spam, etc.
