I appreciate the patch! Esp on a Weds night. I applied and rerolled
dovecot, but I can still move messages into the over-quota namespace.

I threw some i_debug's into quota_roots_equal()  (and one right at the
top), but I don't ever see them in the debug logs. But both "ctx->moving"
and "src_box == NULL" are true, so it never calls quota_roots_equal anyway
in that patched 'if' clause in quota_check. I threw the following into
quota_check and it printed to the debug log for both if's:

        if (ctx->moving ) i_debug("quota: quota_check: YES to ctx->moving"
);
        if (src_box == NULL) i_debug("quota: quota_check: YES to src_box ==
NULL" );


Out of curiosity, in the Quota wiki page, it mentions that 'in theory there
could be e.g. "user quota" and "domain quota" roots'. That's also super
interesting to me. Does anyone have any experience with that? I.e. any
gotchas?
