Your pretty good Dave as that was one of the things I found while 
googlin. What I couldn't find while googlin is who is the culprit?
  Would it be the person sending it? If so, she is our client and always 
uses our squirrelmail via http. Also, why would this happen once in a 
while? Some go through ok and some get rejected (she can successfully 
send to that person sometimes but alot get the missing bracket).
