Upgrade cyrus 2.4.17 to 2.4.18 on Ubuntu

[Patrick Goetz]

I believe the version number change (incremental change to stable 
release) indicates you shouldn't have any problems, but of course shut 
down the service while it's being updated.

Re: Cyrus 3.x packages for Ubuntu:

I thought Debian was the one distro the cyrus crew provided up-to-date 
packages for?  See for example here:

   https://packages.debian.org/sid/amd64/cyrus-imapd/download

Grab the Debian source package and build it on your system for maximum 
compatibility (although the binary packages should be fine.   On Ubuntu, 
just download the debs and install by hand:

   # dpkg -i cyrus-imapd_3.0.8-4_amd64.deb
