We have a free email domain through Zoho, lets call it example.com.
Two questions:
- We created a shared mailbox, let's call it "support@example.com". At the same time, we have a Wordpress site sending emails through Postfix email service to the support@example.com address. The web form is set to send emails using a "from" address matching the shared inbox, support@example.com. The emails sent via Postfix arrive at the shared inbox successfully, however they have a security warning. This could be because we are overriding the "from" address our web server is sending as, which is natively set at apache@prod.example.com (see attached image). What is the best method we can resolve this security warning?
- A group was created under the example email domain, let's call it "sales@example.com". We added two individual mailboxes as for recipients for the group. Using this setup, we have a Wordpress site sending emails through the Postfix email service to the sales@example.com group address. The web form is set to send emails using a "from" address that ties to a shared inbox, let's call it support@example.com. However, the emails sent to the group@example.com group email never arrive, even though we've whitelisted all emails to this group from the "example.com" domain. Does anyone know why this is? Are these security errors (#1 above) a possible reason why emails sent to our group are not arriving?
Thanks for your help.
