OK, I remember now. The problem wasn't symlinks but that mhonarc
generates URLs relative to the current directory. If we have message-id
files outside the directory, links like "Thread Next" will not work. We
could try to change those to absolute with a script. The community
archives are going to have the same problem.

Ahh, thanks for pointing it out. I think I will use an HTTP redirect.

How do you know which directory to redirect to?

I can't see how Apache redirects would work, but I suppose you could use
HTML redirect because you know at the time you are creating the message
file which directory to point to, but again the title bar will change
to relative once you do that.

The script gets the directory as a parameter.
