There was discussion about this last week. You probably set Milter
timeouts in sendmail.mc (INPUT_MAIL_FILTER line) too low. You got large
email, MIMEDefang wasn't able to process it in less than timeout time,
sendmail rejected mail with tempfail (as you instructed it to do when it
timeouts in the very same INPUT_MAIL_FILTER line).
Try raising timeouts to at least 15 minutes. If you are accepting huge
emails (definition of huge 10MB or larger), half an hour or even an hour
(if you don't have any limits on the size of emails you accept) might be
good idea too. More than one hour doesn't make any sense (remote side
will usually timeout after one hour of waiting for response from your
sendmail).
