header corruption very regularly

Some of the spam I'm getting has 



content-lenth: 0



or 1



Yosucker downloads these, gives me the header corruption  message, and marks the message as read but does not delete them.  (behavior As designed?)



But even though they're marked as read, the next time through it fetches those messages again.



Looking at several of these now it looks like the header is valid EXCEPT for 



Message-ID: <D[20



(They're not sneaking control characters in somehow AFICT,

using od

the < shows as 074 

the [ shows as 133)



Here's one complete mail, my  bash prompt is $.  That's 3 newlines at the end, after the 1 in content-length.

I'm solving this now by regularly going and deleting these.
