Description Daniel Roethlisberger 2009-07-03 23:40:05 UTC 
Fix a race condition in the multiple recipient delivery code which
can cause message corruption, sometimes visibly, sometimes silently.

How-To-Repeat: $ dd if=/dev/urandom bs=1k count=100 | openssl base64 > /tmp/data
$ mail -s test your@email.com your_second@email.com < /tmp/data

Notice that dma(8) will bounce the message for some or all of the
recipients and/or that the received messages vastly differ in size
and content from /tmp/data.
