What exact change *in logcheck* could have triggered this? Is there
anythin *in logcheck* I can (temporarily) disable, like bisecting the
difference between the previous version and the current one?
If not, maybe it is better to return to the previous one, as we are in
the hard freeze now[1] …

[1] I don't want my future stable machines to send every mail twice
with an exim error for the next years …
