Re: DNS CONFIG CHALLENGE

Herb,

I thought that @ referred to the value of $ORIGIN, and this doesn't change
unless you specify a new one.

Q: 1 domain name abc.com. 1.1.1.1 hosts web site. 2.2.2.2 hosts
email.
what should my dns config look like?
Current records that don't work cause i'm ignent.
A record:
host=@ points to = 1.1.1.1

@ is NOT a fixed name in a Zone file but resolves to the PREVIOUS
record name -- at the beginning this is the ZONE NAME itself but changes
as the zone file progresses.

You need A records for each of the "main" names of each of those
hosts (1 and 2) and you need either A records of CNAME records
for any additional names (or alias) that those hosts need to support.

You need an MX record for each email server, pointing name to
existing A record (which may or may not be in your zone.)

In the REVERSE zone (at the ISP usually) you need the reverse
PTR records for each email server -- and the names used (by the
ISP) for these servers' PTR records is the name the SMTP server
must report for HELO (in your SMTP config.)

Use the GUI and don't work so hard if you are new to DNS.

CNAME records:
www=@
email=mail.abc.com
mail=mail.abc.com
smtp=mail.abc.com
ftp=@
e=mail.abc.com
webmail=mail.abc.com

MX records:
priority=0 host=@ goes to=2.2.2.2
priority=10 host=mail.abc.com goes to=2.2.2.2
thanks, jho
