Sendmail without FQDN or DNS ?

[bytebit2]

Want to use Sendmail only to send; have no FQDN or DNS set up. Mail gets off the server but never reaches the destination (machine to be used as an in house web server to run a Perl HTML form mail script , or PHP form mail code)

Can this ever work without DNS or the machine with a proper FQDN ?

Logs and play show mail being sent and the scripts running, but, again, mail never getting there; reading I’ve done suggest it’s an authentication /spam issue based on lack of FQDN.

I’d like not to bother with DNS, etc, and just throw the box on a client’s static IP, move the site files and scripts and tell the name server folks to point to the new server.

You can't use sendmail as an smtp server without an FQDN. However, you can set it up to use a 'smarthost'. You would route all your outbound mail through this server. Another thing you can do is configure your mail script to use an smtp account. Most formail scripts have this option. If you do not have an smtp account you can use, you can buy an account. Usually, the cost is based on the amount of mail you send.
