Budget: $10 – $30 USD
We have issues sending email to certain domains who don’t recognize our MAIL host domain server account.
Client host rejected: cannot find your hostname, in reply
to RCPT TO command)
Infrastructure: ZIMBRA WEBMAIL on a CENTOS 6 SERVER and the Network Gateway is a PFSENSE Firewall. They are all in a Cloud environment.
Everything is working fine, the only issue is the email to certain domains who reject email with the message: cannot find your hostname, in reply to RCPT TO command).
WE NEED TO IMPLEMENT A REVERSE DNS FOR OUR INTERNAL MAIL SERVER MATCH OUR DOMAIN
Please: We need someone who understands LINUX, PFSENSE, and ZIMBRA and knowns how to set up a DNS Reverse ARP Proxy to resolve our internal mail name to our external mail domain and email messages wont be rejected anymore.
