a) Is this expected behavior and can it be changed?
b) How can I disable inbox auto-creation if a) doesn't pan out?

Can anybody think of a quick workaround or fix for this, as it's clearly
not intended behavior (nor needed for this issue).

Hello Aki, Timo,
according to git this fix should be in 2.2.27, which I'm running, so I
guess this isn't it or something else is missing.

INNODB STATUS
Current InnoDB index space = 49 M
Current InnoDB data space = 109 M
Current InnoDB buffer pool free = 98 %
Current innodb_buffer_pool_size = 8.00 G
Depending on how much space your innodb indexes take up it may be safe
to increase this value to up to 2 / 3 of to
HDDs. With 4 of them in the RAID10 they will be twice as fast as the 2

This can be tweaked even further with the various RAID 10 layout options,

Also an "iostat -x" oneshot summary and a few samples of when the machine

My current goal is to have 100k capable servers that work well, 200k in a

The later is a single-threaded process, so it will benefit from a faster
CPU core.
It can be dramatically improved by enabling process re-usage, see:
http://wiki.dovecot.org/PerformanceTuning
However that also means more memory usage.

But if you have a system with less reserves, users that access mail
very infrequently but get plenty of mail (so indexing at access time
will be an involved process) and no mass mail spikes, dovecot LDA
