I see in my syslog this (suse.opensuse.devel is a local only
newsgroup filled by my mail2news script):

Feb 28 16:48:45 stitny.cepl.eu leafnode[3017]: LOCAL POST <167759915880.187=
40.10958568344351428460-lx9mn2B4QYRR1hWGu1MpQ8fM928Kxa1hQH7oEaQurus@public.gmane.org> suse.opensuse.devel

ews/in.coming/3017-1677599325-1: "malformatted", moving to /var/spool/news/=

And in the (attached) email message I see

Message-Id:
 <167759915880.18740.10958568344351428460-lx9mn2B4QYRR1hWGu1MpQ8fM928Kxa1hQH7oEaQurus@public.gmane.org>

This looks to me like a perfectly correct email header split over
two lines. That should be correct, shouldn't it?

Best,

Blessed be the God [=E2=80=A6] who comforts us in all our affliction, so
that we may be able to comfort those who are in any affliction,
with the comfort with which we ourselves are comforted by God.
