Everything so far has been working great for me. Thanks! However, I’m having an issue with the ‘myhostname’ and ‘mydomain’. I basically just want to use my mac for local development/testing and only need to send out mail via php scripts. I don’t think I would need to receive mail.

So, can I just use localhost for the myhostname and mydomain? If not, I’m not understanding what you mean by using my primary registered domain. If I go to a domain registration service and register a new domain like ‘somedomain.com’, do I use that for myhostname and mydomain? Would mail then be able to go out (and come in)?

Any guidance you could give would be great!

@Stefan: The phrase you are referring to is grouped with the file list so it should be clear which files I’m referring to.

The second part is referring to the username and password you have defined to access the postfix admin database which you are accessing using this files.

You should never copy the username and password from documentation and always choose different ones. Otherwise you are opening up your system for other outside users.

“Please change the user and password in the mysql files”

What does this mean? Are you referring to the mysql_virtual_xxx_maps.cf files on this page? Please be precise.

“to the one you have configured yourself.”

What does this mean? Configured where? AFAICT, the documentation to this point has used ‘postfix’ for both username and password, so why would you change this here? Please be precise.
