I'm trying to set up an extremely basic mailserver on Leopard 10.5 in order to
check the behavior of some PHP scripts. Nothing fancy needed - I just want to
send and receive mail to/from myself without having to go out to my ISP.
QUESTION #1
I've been able to get Postfix started and can telnet into 127.0.0.1 to get a
test email sent. The issue is that it bounces as an unknown user...is there a
basic checklist I can run through to make sure the user does in fact exist? I
can only find buts and pieces on the web.
Here is the error message I'm getting:
to=<j...@john-does-imac.localhost>, orig_to=<j...@john-does-imac>, relay=local,
delay=0.07, delays=0.06/0/0/0, dsn=5.1.1, status=bounced (unknown user: "john")
I modified /etc/postfix/aliases:
root: john
then ran newaliases, but that doesn't seem to help.
QUESTION #2
I know that I need an FQDN in order for Postfix to function properly, but I'm
having trouble understanding what goes where in the "u...@host.domain.tld"
scheme.
My System Preferences list the following:
Computer Name: John Doe's iMac
Computers on your local network can access your computer at:
john-does-imac.local
Assuming I want to send a message to johndoe, what does the FQDN look like? How
about the following parameters?
myhostname =
mydomain =
myorigin =
The confusing part is what to use for the domain and tld since I don't own an
actual domain like "yahoo.com". My best guess is:
j...@john-does-imac.localdomain.local

Any help would be appreciated. Thanks.
