Could you please paste the full bounced mail content? It contains technical details about why mail failed.

Also, do you have correct A/MX records in DNS for your mail domain name?

*) Is 'phx.gbl' your mail domain? It doesn't have A and MX record in DNS.
*) We need bounce message returned by mail sender, not the email you composed.

Deleted details/message as matter is resolved.

Please stop telnet service, and don't forward port 23 to 25.

I cannot connect to your server with telnet command (not telnet service):

I checked port 25 of your server, looks like it should work now:

$ telnet 24.73.226.66 25
Trying 24.73.226.66...
Connected to mailserver.ormondkwikstop.com.
Escape character is '^]'.

Did you try to send some more testing email from Gmail/Yahoo/Hotmail/...?

It's better to check document provided by your SSL provider.

Also, you can search this forum, many users shared their settings.

I went to StartSSL.com web site and their instruction is:

Apache Web Server

First of all you have to load the mod_ssl module. Many distributions and packages have this module shipped by default, otherwise check the documentation of Apache how to do this.

To configure a default SSL/TLS aware virtual server, you should add at least the following lines to your httpd.conf or ssl.conf file:

    LoadModule ssl_module modules/mod_ssl.so

    Listen 443

    <VirtualHost _default_:443>
       DocumentRoot /home/httpd/private
       ErrorLog /usr/local/apache/logs/error_log
       TransferLog /usr/local/apache/logs/access_log
       SSLEngine on
       SSLProtocol all -SSLv2
       SSLCipherSuite ALL:!ADH:!EXPORT:!SSLv2:RC4+RSA:+HIGH:+MEDIUM

       SSLCertificateFile /usr/local/apache/conf/ssl.crt
       SSLCertificateKeyFile /usr/local/apache/conf/ssl.key
       SSLCertificateChainFile /usr/local/apache/conf/sub.class1.server.ca.pem
       CustomLog /usr/local/apache/logs/ssl_request_log \
          "%t %h %{SSL_PROTOCOL}x %{SSL_CIPHER}x \"%r\" %b"
    </VirtualHost>

Download the sub.class1.server.ca.pem for the above configuration. Make sure to change the path according to your apache installation. For windows you need to use something like c:\apache\httpd.

If you have a higher validated server certificate you need to use the class2 or class3 intermediate CA certificate.

I pasted code from "LoadModule .................</VirtualHost>" in /etc/apache1/httpd.conf file with certificate apppropriate path (/etc/ssl/private/) for key and certificate but then I cannot access https://your_server/mail/, I end up getting site unreachable error. Any suggestions?

The only reason I copied the code is due limited ability to modify proper files. StartSSL.com suggested to paste the code in httpd.conf file and that's why I did it but it had side effects. Now, per your suggestion, I have all those 3 files in my /etc/ssl/private directory, but do I just insert three lines of code in httpd.conf? I will give it a shot and see what happens.

Regarding, paid remote support, I have that option open but, I just want to learn and do it myself. I must tell you that iRedMail has been the EASIEST deployment of all tutorial out there on the web and your support has been exceptional. I have been reading for past three months to set up mail server but trust me it is too much to digest for a novice like me.
