Re: Email with Dynamic IP address

Owen,

Would you tie in a POP3 connector service when there's a backup MX
hosted somewhere else? Maybe checking in every 1 or 2 hours?

The reason I ask, is because if you didn't have the POP connector
running, albeit redundantly, then how would you even know that there's
mail on the second MX server that needs to be retrieved?

So if my domain name is www.domain.com :

I should add the name for exemple domain.dyndns.org for my DNS resolution
and create a mx record in the dyndns configuration for exemple mail.
domain.com.

Is it enough or I should do something else ?

Actually, you need to update the MX record(s) associated with
www.domain.com so that the highest priority one points to
domain.dyndns.org (or whatever name you have associated with the dynamic
IP). Depending on how and with whom you registered domain.com, you may
be able to do this yourself or you may need to ask your DNS provider to
do it for you.

After that's done, mail sent to someone@xxxxxxxxxx will cause an MX
record lookup for domain.com. That will find domain.dyndns.org as the
highest priority mail server and the mail will be sent to user
"someone" at the IP associated with "domain.dyndns.org", which should be
your SBS.

You should strongly consider creating lower priority MX records to a
"backup MX" server, which most ISPs and dyndns services can do for a
modest fee. This will avoid mail loss if your server is down or your
Internet connection is unavailable (not uncommon with cable and DSL
providers).
