Hi Jamie, the new dovecot module didn't get installed
with 1.240. There was no problem to add it from the
standard modules collection. Happened on all machines
I don't see an option to disallow installing completely
new modules, so it must have definitely been left out
from the install.
Ah, I left the "don't reinstall deleted modules"
unchecked with another machine, et voila, I got the
Dovecot module. It seems, this option doesn't install
*any* module that is not already present. But it
shouldn't do this for completely new modules.
