I am trying to add trusted mail accounts for 3 days and/or trusted local ip address to zimbra server.
I have some servers to send automatic e-mails to distribution list on zimbra server. I have some accounts defined on Zimbra server to send automatic mails to defined local distribution list or single local accounts.
For instance, in my local network I have a fax server and this fax server can send mails when receive fax. I configured fax smtp server to send e-mails to defined fax account on my zimbra server.
When I try to send mail from fax server, always getting following error:
NOQUEUE: reject: RCPT from unknown[220.127.116.11]: 554 5.7.1 <unknown[18.104.22.168]>: Client host rejected: Access denied; from=<qdms> to=<email@example.com> proto=ESMTP helo=<mail.yatas.com.tr>
By the way, Zimbra Server is located on DMZ area, all users have to access to this server via firewall.
By using MTA, I add fax server's external ip (22.214.171.124) and local ip address (10.0.2.32) to Trusted Networks but still getting same error msg.
Instead of adding trusted networks if we can add single trusted e-mail address, this will work, too. But couldn't find how to that...
Can you show me the way to solve this problem?
With my kind regards,
