Greetings,
DNS seems to stump more people than anything else, yet it's
quite simple....
First, forget cnames. They'll just get you in trouble. Think in terms of
machine name and mail exchanger (MX) records.
What's the name of the machine your mta is on. No matter what the original name
of that machine, you can declare it as mail.domain and assign it any address you
want (assuming the address belongs to you). If you are the authoritative DNS
host for andigilog.com, you can put records for andigilog.com in the zone file
and they'll be valid.
(If you don't like mail, use any name you like)
Along with declaring the address record for mail, you can use the MX record to
point to the location of the mta. Of course, the MX record pointing to a
specific domain can be used in any DNS zone file, not so for the A record.
IF you try to claim authority for a DNS zone and someone else really is, you
have created a "lame delegation"
If you are trying to receive mail for andigilog.com and there is no MX record
in the AUTHORATATIVE DNS zone file pointing to you, forget it. You will have
trouble receiving any mail for andigilog.com, if at all.
Sorry if it seems like I'm ranting.... I do a lot of DNS and I see so much wrong
information and nonunderstaning that it drives me up a tree.
If you have a DNS question, direct it to me personally. I'll give you the best
answer I'm capable of.
Regards,
Eric
