[Mimedefang] EOM ACK/NAK timeout

[Andy Lyttle]

Hey all, I've been noticing this in my logs:

milter_data(mimedefang): EOM ACK/NAK timeout
Milter (mimedefang): to error state
Milter: data, reject=451 4.3.2 Please try again later

One particular message (which looks legit, not spam) has been  
retrying 94 times since yesterday and is getting this same result  
each time.  Help!  What can I do?

Thanks!
