1. Have your ISP create a reverse pointer to your domain
(mail.mydomain.com)

2. Use or domain's registry for DNS - you will have enough
headaches. Create an A record mapping mail.mydomain.com to your IP.

3. Consider Postfix rather than sendmail.

4. AFTER you have the reverse pointer, see which DHCP blacklists
(including mine) list your IP. Request removal - politely, please.
