[My apologies if this is considered off-topic; this is a one-off posting]
I would like to announce the availability of a preview release of "Linnet".
Linnet is a pre-compiled, pre-configured and ready-to-run mail server
bundle, comprising exim, courier-authlib, courier-imap, sqwebmail, apache,
openldap, openssl and ruby. It also contains a simple command-line interface
for installation, stopping and starting daemons, and updating userdb
entries.
The exim configuration by itself may be of interest: it combines much of
Tony Finch's excellent Cambridge University configuration (including ACLs
and "personality" selection), with my own authenticators and routers which
communicate with courier's authdaemon.

Linnet can get user data from either userdb or an LDAP database, or both. It
supports clustering using a 'mailhost' account attribute for directing
incoming SMTP/POP3/IMAP connections to the correct machine in a cluster.
Linnet is designed to be easy to install and risk-free to upgrade. Multiple
versions can be installed at once and you can switch back and forth
instantly between them. Key libraries are included in the bundle (in
particular, openssl, openldap and Berkeley db), minimising dependencies on
the underlying O/S. Config files in Sam Varshavchik's sysconftool format
allow automatic merging of settings when updating.
Linnet builds from original source tarballs using ruby scripts; I have also
released binary builds for FreeBSD 4, FreeBSD 5 and Linux.

The documentation is very incomplete at present but should give enough
information for anyone who is interested to try it out. Please send feedback
via the linnet-users mailing list:
