I've rebuilt and reinstalled without striping the binaries.  I'm still
getting signaled to death, but haven't gotten a new core.  Grr.

Just take it out of sasl_mech_list?  I just did that.  Now iCal doesn't
seem to be able to authenticate, keeps asking for the password.  But,
the Lightning plugin for Thunderbird can.  Lightning seems to be
trying to post to the test calendar I created a couple of days ago,
PersonalTest1.  I'm pretty sure I manually created that folder with
cyradm as part of my troubleshooting of the signal issues.  Lightning is
being denied permission to PUT the .ics.

Maybe I've hosed things up by manually creating folders.  Can I just
use cyradm to remove everything in #calendars?  Should I take out the
#calendars folder itself?

I would just do it, but don't want to mess up the process if it's the wrong action.
