When reading through main.cf and configuring postfix I am unsure of which domain, origin and hostname values to use.
For example say our public domain is mydomain.com and we have a certificate for mail.mydomain.com and our MX points to mail.mydomain.com Our mail server called hermes runs our our lan who'se domain is mydomain.local In main.cf is: myorigin hermes.mydomain.local or mail.mydomain.com myhostname hermes or mai dydoman mydomain.local or mydomain.com Thanks in advance...
