Ahh, the wonderful world of cheap VPS.  If this is a "dedicated" server,
how are they preventing you from replacing the kernel image?  You have
root access don't you?  Then there should be nothing stopping you from
updating the kernel.  If they can physically prevent you from doing so
then this is certainly NOT a dedicated server platform, but a hybrid VPS
hosting platform.

As your problems are very unlikely caused by Dovecot, but by the Squeeze
upgrade, I'd suggest you take this up on the Debian users list.  Someone
there may be able to give you more insight.

BTW, does your VPS provider support Squeeze?  Did you ask them before
upgrading?  It would appear they don't yet support Squeeze...

Good luck.
