[Imap-uw] MX Folder Support

[Erik Kangas]

Hello,

We are considering using the MX folder driver in mailutil to export mix 
and mbx folders into a 1-message-per-file format
 that can be easily read by Outllook-related programs, thunderbird, 
etc.  This works well in our tests (especially if you remove the 
.mxindex file and append a ".eml" to the end of each message file 
name).  The two questions I do have are:

* The docs in the uw imap distribution inducate that "mx" is 
experimental, not to be used, and may be removed.  Is there any real 
expectation that this driver will be removed from the distribution in 
the foreseeable future?

* The syntax for specifying a new MX folder is different than for other 
formats it seems.  If one is "root", it seems that you can not specify 
just any absolute path as a new MX directory.  You can use 
/tmp/foldername or /foldername, but /some/long/existing/path/foldername 
may return an error that it is an invalid MX folder name.  I can live 
with this, but I don't see where the "valid MX folder name" is specified 
so I can understand the exact set of allowed names.

Thank you,
