newbie question about postfix mail

Help! (Home for newbies)

hi all -

this is a really idiot-newbie question, so i apologize in advance.

what do the dns-zone records look like to use the Postfix mail server?

i have tried the following:

@	IN	SOA	ns1.edwardsmarkf.com. root.ns1.edwardsmarkf.com. (
			1335369325
			10800
			3600
			604800
			38400 )
@	IN	NS	ns1.edwardsmarkf.com.
edwardsmarkf.com.	IN	A	69.10.48.25
www.edwardsmarkf.com.	IN	A	69.10.48.25
ftp.edwardsmarkf.com.	IN	A	69.10.48.25
m.edwardsmarkf.com.	IN	A	69.10.48.25
localhost.edwardsmarkf.com.	IN	A	127.0.0.1
webmail.edwardsmarkf.com.	IN	A	69.10.48.25
admin.edwardsmarkf.com.	IN	A	69.10.48.25
edwardsmarkf.com.	IN	TXT	"v=spf1 a mx a:edwardsmarkf.com ip4:69.10.48.25 ?all"
mail.edwardsmarkf.com.	IN	A	69.10.48.25
edwardsmarkf.com.	IN	MX	5 mail.edwardsmarkf.com.

but the email is returned in error looking like this:

This is the mail system at host server.edwardsmarkf.com.

in my defense, i have been using google-apps email for years and years now, but yesterday we learned the google empire is no longer going to give away free accounts. so now i have to get serious about hosting my own email server!

I suppose the destination verified if the sender domain (here: “server.edwardsmarkf.com”) has an MX or A entry. You need to add that to your zone, or change the sender address.
