I'm setting up Citadel using the instructions from the library but I've hit a snag. Everything went smoothly but I can't access the web interface. Here's the deets:

• I host websites on this linode (with apache,) so I set the citadel ports to 8080 and 4343 as recommended.
• My hostname on the machine is set to mail.domain.com.
• The reverse DNS on the linode is set to domain.com
• I have two MX records in the linode DNS zone:
  • domain.com
  • mail.domain.com (subdomain: mail)

I did something wrong with the DNS, right? Any help would be appreciated.

I figured it out. There also needed to be an A record for mail.domain.com.
