Description Jan Lieskovsky 2010-03-10 17:22:46 UTC
Dovecot upstream has released latest v1.2.11 version:
  [1] http://www.dovecot.org/list/dovecot-news/2010-March/000152.html

addressing one denial of service issue (from upstream announcement):
"mbox users really should upgrade, because by sending a message with a
huge header you could basically cause a DoS (this problem exists only
with v1.2.x, not with v1.0 or v1.1)."
