hi,  
  when I send mail with msmtp,it take this error message to me :

 msmtp: envelope from address xxx  not accepted by the server

msmtp: server message: 553 authentication is required,smtp7,DsmowECZ_U6a66pQw8i2Ag--.525S2 1353378714

msmtp: could not send mail (account default from /usr/local/msmtp/etc/msmtprc)

the msmtp config file is right seted,host address and account is seted correctly!


is there some advise?
