[Mailman-Users] mails send from sendmail with commandline to mailman become 'Message has implicit destination'

[MichaelLeung]

Hi Mark

normally , dovecot service will save a copy of mail that i sent , but , 
mailx won't ,

i was using mailx to sent those test mails to you , so , there were no 
raw message left in my mail server

from the message that you received , there is nothing wrong with the 
spoofing mail(test mail 1)

remeber i said i have two mail servers and one client machine,

i sent those test mail to these two mail servers , one accept test mails 
just did as yours , another one (the one are fixing ), lost the To: and 
subject:header.

i start to believe that is my sendmail service's problem.
