I've successfully mapped domains to WP MU subdomains using parked (pointer) domains.
However, I need to use a secondary domain (instead of a parked domain) for custom email accounts, according to my host Nexcess.
[Nexcess tech support, btw, has not been helpful.]
So, when I create a secondary domain to send supercool.com to supercool.mysite.com, one of two things happens:
1. supercool.com is just a Nexcess holding page, not my WP MU site.
2. If I turn on .htaccess in Siteworx, it gets stuck in a forwarding loop between supercool.com and supercool.mysite.com.
Suggestions? Hints? Tips?
All would be greatly appreciated.
