I have three mail address in my contact book ,there are:
"David Chang" <david at tmv.gov.tw>
"D.C"                 <david at tmv.gov.tw>
"TEST"                <test at tmv.gov.tw>

Now i grouped them into a list,called "friends".

My problem is ,if i put the list "friends" to RECEIPT and send
it(sednmail),i will have a  return error message,ref attachment. And none of
them got this mail.

Once use these three mail address instead of friends,it work fine.If someone
confirm this i will create a bug ticket,thanks.
