dovecot - Jan 2012 - Migration to multi-dbox and SiS

Dear list,

A huge thank-you first of all for all the work that's gone into Dovecot
itself.

I'm rebuilding a mail server next week and so, taking the rare opportunity
to re-consider all the options I've had running over the past couple of
years.

Around the time of the last re-build (2010), there had been some discussion on
single instance storage, which was quite new on Dovecot around then. I chickened
out of setting it up though. Now with it having been in the wild for a couple of
years, I wonder, how have people found SiS to behave? Additionally, though there
was talk of the prospect of it being merged with 2.x am I right in thinking
it's not yet in the main project? Couldn't find any 2.x changelogs that
could confirm this.

With best wishes,
Ronald.

It's in v2.0 and used by at least a few installations. Apparently it works
quite well. As long as you have a pretty typical setup it should work fine. It
gets more complex if you want to spread the data across multiple mount points.
Backups may also be more difficult, since filesystem snapshots are pretty much
the only 100% safe way to do them.

BTW. SIS, not SiS ("Instance", not "in")
