Are you using a locally hosted mail server on a Dynamic IP? If so you configure your SMTP as a relay to your own ISP's SMTP server. This is only required for OUTGOING mail but you will need to configure using an authenticated account on your ISP.

otherserveraddedomains.com also has to have reverse dns setup since that is the domain sending the mail. Even though the mail server itself already has reverse dns. Each domain for mail being sent has to reverse resolve back to the correct ip.

Which is YOUR domain name where you are hosting the mail server? Use this site (https://mxtoolbox.com/) to see if it can give you further information.
