Hi Mike,
many thanks for your reply.
I do not see anything dramatic on this machine, I also assume that 2GB free
harddisk space are enough for the upgrade:

Also dovecot work (I received your email through that installation), my
interpretation is that the install failed early enough (pre-rm script):
rd@netcup:~$ apt-cache policy dovecot-imapd
dovecot-imapd:
Installed: 1:2.2.13-12~deb8u6
