received help from Sonicwall support

<div class="content wysiwyg-content">
We recently changed firewalls to a Sonicwall 2400. When smartphone users try to connect to our mail server they get an error. TestExchangeConnectivity.c<wbr />om shows the following error:<br />
<br />
&nbsp; Additional Details <br />
&nbsp; Host name mail.ourdomain.com doesn't match any name found on the server certificate CN=10.0.0.2, OU=HTTPS Management Certificate for SonicWALL (self-signed), O=HTTPS Management Certificate for SonicWALL (self-signed), L=Sunnyvale, S=California, C=US. <br />
<br />
I don't think we had any sort of certificate on the old firewall, but can't be certain. Our mail server has the right certs.<br />
<br />
Is there a way to get the Sonicwall out of the cert business entirely? If not, what are my options. I tried importing the certs on the mail server to the firewall, but it didn't solve the problem (though I could have done it incorrectly....)<br />

Cert issue after installing a new firewall

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.

HTTPS is a protocol for secure communication over a computer network which is widely used on the Internet. HTTPS consists of communication over Hypertext Transfer Protocol (HTTP) within a connection encrypted by Transport Layer Security (TLS) or its predecessor, Secure Sockets Layer (SSL). The main motivation for HTTPS is authentication of the visited website and to protect the privacy and integrity of the exchanged data. HTTPS is widely used for protecting page authenticity on all types of websites, securing accounts and keeping user communications, identity and web browsing private.
