You shouldn't have to use a nnmaildir-server in Gnus just for mairix. In
fact, I guess this is the reason for the problems you describe. For
nnmairix to work, your search folders must be on the same backend as
your "real" mail folders (in your case nnml). Maybe I should this make
more flexible, but I thought it makes the setup easier.

Mairix should work directly with nnml. Simply use 

base=...your base folder for your nnml directories...
mh=...folders you want to index...
mformat=mh

in your .mairixrc. 

When you create the nnmairix default server, choose the nnml server as
your mail backend. (Before you do this, delete your old nnmairix server
by killing all nnmairix groups and restarting Gnus).

I'm not sure about your mbox-files you use with nnfolder, though. But I
guess you could simply include them with 

mbox=...your mbox-files (relative to 'base')...

in your .mairixrc and it should also work with nnmairix. There is one
drawback to using nnml with mairix, though: the article count will often
be wrong (but will be corrected as soon as you enter the group). I think
this could be quite easily fixed in mairix itself (it simply has to
output consecutive article numbers).

This is because you specified the nnmaildir-server as your mail
backend. However, mairix will put the search results under the path you
specified with the 'base' variable in your .mairixrc. 

Maybe I should better explain how nnmairix.el works: When you create the
default search group with the name "search", it creates the group
"zz_mairix-search-1" on the "real" mail backend which you specified
(e.g. nnmaildir:MYSERVER). When you query mairix with a search term, the
binary is called with "-o zz_mairix-search-1", i.e. mairix will put the
search results into the folder zz_mairix-search-1 under the 'base'
directory. 

This means, the 'base' path in .mairixrc and the base path of your mail
folders have to be the same.
