Sorry I meant the manual, the confusing part is the hostname.. I used my FQDM when doing the install so I chose mail.mydomain.com and then postfix wanted the hostname so I gave it mail.mydomain.com.
I'm getting ready to do a fresh build now and to avoid any errors, just so I'm clear I set the hostname as mentioned above, but for the postfix portion when it asks for the hostname what value should I give it?
Last but not least, and I do apologize for my ignorance. The DNS values when installing are they the ISP or the DNS server my url is registered with?
Thanks for your patience and for being available to help!
