That's not the "From:" RFC5322 message header, it is the prepended "From
" (no colon) line that acts as a delimiter for mbox files. That's good,
because that line contains the envelope sender, which the "From:"
message header may not.

Provided Exim is properly adding the no-colon From line to messages that
it pipes into dovecot-lda, there should be no change.
