Thanks!Installing Squrrel mail need IMAP server

I have been trying to get a reasonable installaton of Squirrelmail running. One of the questions asked is what type of IMAP server Dreamhost uses. My installation also doesn’t seem to show multi-type messages correctly, they come through with the content-type header missing so all you see is HTML source code. I understand that Squirrelmail gets this information from the IMAP server. I also cannot get the HTML-email plugin working if anyone has tried that.
