There's support for that. You have to read a few drafts and RFCs, though.

The draft in question defines a sort command and some sort keys, and it 
permits defining more sort keys. Other documents allow defining 
collations (sort orders) and using them im IMAP.

Sorting by From field the way most MUAs do requires defining a new 
collation and a new sort key, since this draft's "from" key uses only 
the localpart ('arnt' in the case of this message). Personally I think 
that sort key isn't at all fortunate, but it's too late to change that. 
There's decade-old running code already and the most important thing is 
to document the deployed extension.
