Hi !!

you can also use $message_size to distinguish between callouts and
bounces at rcpt time. If $message_size is greater than zero then
the message is a bounce and you could reject it at this stage without
affecting callouts, if not then it's either a callout or a bounce
from a remote client that does not use SIZE and it will be better to
reject it at predata
