Jacob, You might have a look at the mini-HOWTO titled: Sendmail-Address-Rewrite This walks you through setting up your sendmail.mc file for situations where you are using a dial-up connection where your domain is not on the internet. There's more to it than just a smart_host. You need to set up a genericsdomain and a genericstable in your /etc/mail directory. I can help if needed. Chris
