DNS & Bind, sendmail, Mailman, and Apache, is it all possible w/o a static IP?

I reciently installed RH9 and was hoping to have it serve as my mailserver, run Mailman,vsftp, and possibly host a small website.
I own a .com. My IP is assigned by my ISP, its not static, but it has not changed in the 2 years I have had the service.
Am I barking up the wrong tree? Is it possible to configure the RH9 server to have the .com resolve to it, have sendmail recieve all the mail going to that .com, and host that .com website?
I'm prepared to spend some time researching this information, but just wanted to be sure I'm thinking along the right lines here.

BTW - I already picked up O'Reilly's DNS and Bind and sendmail books, just wanted to know if theyre going to be useful

Thanks for any information you can provide!

Yea its definitely possible, as long as your name server supports dynamic updates, if you're running one yourself make sure you're able to do dynamic updates to the top level com. domain.

Or alternatively you can use a free DNS service such as , it provides scripts that you can run periodicaly to dynamically update your DNS records. I use it, it has been very reliable so far.

Since you're running it all on your own server I'd imagine you probably just need to have a Type A record, for example pointing to your box, and have a MX record plus some CNAME records(aliases) pointing to it if necessary(eg., etc). Then you setup a cron job to execute a script that updates the record periodically say every 6 hours, have your MTA configured to receive mails for your domain, then hopefully everything should be running happily afterwards.
