You are reporting a problem with a antique?
Please try current stable version and if problem persist let us know
with include the dovecot -n output.
Current version is 2.2.18, pretty pointless trying to look for a bug
resolution in such a old version, also, 2.1.9 maybe latest in your
distribution but that is not dovecot problem, dovecot does not produce
binaries for any distribution.and you are likely many many bugs in
your 2.1.9 version that long been fixed.
