[Dovecot] Line length limitation in dovecot leads to out-of-control process?

[Amelia A. Lewis]

A follow-up:

The messages are roughly the same length on both machines.  +2 on the
copy-to machine (added LFs, I guess).  It turns out that on copy, the
to-line-from-hell is truncated, then continued (but without a space at
the front of the "added" line, and truncation in mid-word),
lather-rinse-repeat (original is 16504 long, so that's two by 8192 and a
trailer).  Problems therefore could be because the line ends abruptly,
or because the two lines introduced are not valid header lines.

Amy!

I have spent nights with matches and knives, leaning over ledges, only 
two flights up.  Cutting my heart, burning my soul.  Nothing left to
hold.  Nothing left, but blood and fire.
