That is what the mixcvt program does.  mailutil is a general tool and is 
less than fully satisfactory for the purpose of converting to mix format. 
mixcvt is a special purpose tool designed to make a well-formed mix 
mailbox from the source mailbox.

Besides preserving the UID regime, mixcvt also splits the message store 
into multiple ~1MB data files, whereas mailutil will make a single 
gigantic mix data file.

Last, but not least, mixcvt can take mix files as its input; this is 
useful if you want to consolidate tiny data files (as the result of 
expunging) into large 1MB data files.
