Ups. I have to admit that I didn't check the sources. But in the past
there have been a lot of articles with relative short physical lines (say
less than 80 characters) but several folded lines that caused the error
message and increasing MAXHEADERSIZE solved the problem.
One old example is
which was discussed (in German) in

You see that this is an old topic for me but I cannot reproduce it in
2.4.x now - in 2.3.2 (Debian stable) the problem exists if the header is
"References:" or "Subject:", however a test article will pass with an very
long "X-Something:" header.

Seems like I'll have to dig the sources why this happens and whether this
is really still a problem in 2.4.x. If there was a major change to avoid
such problems, silently forget my initial message in that thread, thank

Hm, this could become an interesting method to transmit binaries in
non-binary groups then.
