I am running CentOS 6.3 (Final) 11.0.9 Update #13 It's a fairly new installation with only a handful of micro updates being applied. I am experiencing an odd problem which seems to be a two part issue. 1) If you go to any of the domains and try to load webmail it looks like the subdomain isn't loading PHP. My web browser prompts me to download the PHP files and when I look at the downloads they are in plain text including the code. 2) Any domain set up on it's own dedicated IP is trying to load the main domain website instead of Horde. Basically the DNS is forcing the subdomain "webmail" to be a wildcard for www. Ive tried changing the IP in the DNS records to use the servers Primary IP but even if I restart apache or bind (even cleared my browser cache and rebooted) it still points webmail to the dedicated IP.
