It seems that the problem occurred after Debian/Testing dovecot's upgrade
from 1:2.2.36-1 to 1:2.3.2-2.  I have fixed the problem by downgrading
dovecot to version provided by Debian/Stable (1:2.2.27-3+deb9u2).

I use dovecot in "server less" mode (IMAP via stdin+stdout) with maildir.

mail_location = maildir:~/Maildir:LAYOUT=fs
