I have PHPlist installed on one server, domain MyWebsite1.com, but the web host only allows 100 emails sent per hour. So I am thinking of installing the PHPList on another one of my servers, with a different domain, MyWebsite2.com - a web host that allows more per hour.

Will this be a problem? Will the emails be more apt to be considered spam as they originate from a different domain name?

Thanks for any help!
