managed to get into an infinite and fairly fast (~100
per minute) email loop. As far as I can tell, roundup's
response to being unable to send an email is to send an
email with the entire text of the email it couldn't
send. No prizes for guessing how big the emails got..

Error message enclosed below.  I was running 5.2 on
linux (RH7.3)

Thanks for writing roundup.

Sound like the fix should be a check if that email comes
from a robot
or this roundup instance itself. Usually this is done adding
an X-Loop header
and checking for it.
