cyrus-imapd-2.2 and libdb

[Duncan Gibb]

Hi

Hope you don't my chipping in.  I saw Sven's reply to your email on the
cyrus maintainers list.

I'm "maintaining"(ish) a 2.3.x branch which I hope will make it to full
package status for Squeeze release.  Work on upgrading from 2.3.13 to
2.3.14 is on going.  The discussion wrt which BDB version to use for
that is ongoing in that there have been posts about it on the list this
month, and I at least have more to say RSN.

The summary is that AFAIK, 4.4 is the newest version thus far proven in
the real world.  4.6 will probably by OK for Lenny-backports, and there
are issues to be addressed, possibly upstream, before we can use 4.7.

Indeed.  This needs a lot of attention and testing before we can make a
2.3.x package which is an upgrade path from 2.2.x, and not just one
suitable for new deployments.

Cheers
