From Elendor
Syntax: +MAILSORT [@<altname>] {AUTHOR | SIZE | SUBJECT | TIME} This command resorts the mail in your mailbox by the indicated field. For example, specifying AUTHOR sorts it alphabetically by author. It's most common use is to resort your mail by TIME if somehow it gets sorted out of order. Example: +mailsort time (Sorts the mail in your mailbox from least to most recent date of writing.)
