Others reply like:

* 1 FETCH (UID 1 RFC822.SIZE 123456 BODY.PEEK[HEADER.FIELDS (xxx)]{100}
From: foo
To: bar
)

Dovecot replies like:

* 1 FETCH (BODY.PEEK[HEADER.FIELDS (xxx)]{100}
From: foo
To: bar
  UID 1 RFC822.SIZE 123456)

Both are valid from IMAP point of view so it's Thunderbird's problem 
that it doesn't parse the replies correctly.

It's a bit easier for Dovecot to reply the way it does now, and I'd 
rather not change it just because one client has problems reading it 
correctly. This patch would anyway fix it:
