 500 is probably stretching the capabilities of much software.  Most mailers
pass the message to the transport (MTA) as arguments, and 500 may exceed
the max allowed.

 If you are running sendmail as an MTA, the easiest way may be to
extract the 'From:' lines and make each into a 'Bcc:' line for the
new message which you then feed into 'sendmail' with the '-t'
option (which implies that the recipient addresses come from 'To:'
'Cc:' and 'Bcc:' headers.)  You message can also include a 'To:'
with a group name - 'To: multiple_recipients:;' to make sure
an 'Apparently-To:' in not generated.

 Very difficult.  Probably beyond the abilities it awk, sed, etc.  If
Larry Wall happens to be reading this he may suggest perl.  The trouble is
that the syntax of RFC822 addresses is quite complex, and as X.400 gateways
become more common the extreme cases of RFC822 addresses are increasingly
likely to show up.
