There was an off by one bug which caused a segfault in cyrus-imapd-2.0.6, that has been fixed in 2.0.7 which just has been released, please include this release in the 7.0 powertools, the 2.0.6 will be useless otherwise. Also, I 've heard rumors that openssl will be included in 7.0, does that mean that --with-openssl will be turned back in things like cyrus-imapd and cyrus-sasl ??? Thanks.
Version 2.0.7 has now been added to our build tree.
