Because iconv has much better results and succeeds in much more cases than
mbstring. Normally.

This is correct because iconv doesn't know about utf7-imap, only mbstring.
Thus all folder name conversions in IMP will be done by mbstring (if
available) and most of the message conversions will be done by iconv (if
available).
