Over the past few days I tracked down an interesting issue that was preventing certain items on mailing lists (specifically bug reports) from propogating to upstream news servers and therefore

The problem that took forever to isolate? Trailing whitespace on the Message-Id header line after the > was causing the message to get rejected.

This seems absurd to me. What ever happened to Be liberal in what you accept -- and conservative in what you send?
