Not necessarily. The Sendmail configuration in all the systems I use doesn't have hardcoded IP addresses _anywhere_. Sendmail can rely and usually *does* rely heavily on DNS for providing information about the IP addresses. The default FreeBSD setup uses the file /etc/mail/local-host-names as a list of hostnames or domain names for which delivery will be done 'locally', but that's pretty much all of it. Can you provide more information about the particular email & DNS setup? If yes, then after you give us all the details of the setup you currently have, what you are trying to achieve, whaty you have tried so far and what has failed (including any interesting logs, configuration files, etc.) we will certainly be able to give you more substantial, to the point and correct help :) - Giorgos
