Hi all, I have a strange problem and I cant understand how to solve it. I'm looking for a simple command to send a file by email. I found mutt and I checked it. I'm thought that it was vary well for my job. So now I use export EMAIL="my name <myaddress@domain" mutt -n -a filename -s "subject" dest_address@domain < /dev/null Now I need help solving a big problem (big is for me). I configured local sendmail to use an authenticated smtp. I have 3 email address mail1@domain1 mail2@domain2 mail3@domain3 This is a table changing sender and receiver SENDER RECEIVER RESULT mail1 mail1 received mail1 mail2 received mail1 mail3 not received mail2 mail1 received mail2 mail2 received mail2 mail3 not received mail3 mail1 received mail3 mail2 received mail3 mail3 not received Ok, it seems that domain3 is not working, but if I use evolution to send to mail3 it works well. Also if I use sendmail -F"nome" -f"mail1" -v mail3 test messages . it arrives to mail3 I cant understand what is not working (maybe that I need to set some other environment var, but I don't know). There is someone that can help me? Tnx Ambrogio
