resolving email addresses

[James D. Parra]

Thanks Derek,

How would I have the server find the MX records?


This is the forth MailScanner I built and previous three didn't have that
error. Interesting though. I do see the Feature setting, I think. Is this
it?
FEATURE(`relay_based_on_MX')dnl

Thanks again for your help.

James

You may have a feature of sendmail turned on which doesn't accept email from
addresses which don't have MX records.

Can the server find MX records for the domain?
