Most people need to change two values when trying to correctly forge the from address on an email   First is the from address and the second is the orig-to address   Many of the solutions offered online only change one of these values   If as root  I try a simple mail command to send myself an email it might look like this   echo  test    mail -s  a test  me noone com  And the associated logs   Feb  6 09 02 51 myserver postfix qmgr 28875   B10322269D  from  lt root myserver com gt   size 437  nrcpt 1  queue active  Feb  6 09 02 52 myserver postfix smtp 19848   B10322269D  to  lt me noone com gt   relay myMTA x x x x  25  delay 0 34  delays 0 1 0 0 11 0 13  dsn 2 0 0  status sent  250 Ok 0000014b5f678593-a0e399ef-a801-4655-ad6b-19864a220f38-000000    Trying to change the from address with --   echo  test    mail -s  a test  me noone com -- dude thisguy com  This changes the orig-to value but not the from value   Feb  6 09 09 09 myserver postfix qmgr 28875   6BD362269D  from  lt root myserver com gt   size 474  nrcpt 2  queue active  Feb  6 09 09 09 myserver postfix smtp 20505   6BD362269D  to  lt me noone gt   orig to  lt dude thisguy com gt   relay myMTA x x x x  25  delay 0 31  delays 0 06 0 0 09 0 15  dsn 2 0 0  status sent  250 Ok 0000014b5f6d48e2-a98b70be-fb02-44e0-8eb3-e4f5b1820265-000000    Next trying it with a -r and a -- to adjust the from and orig-to   echo  test    mail -s  a test  -r dude comeguy com me noone com -- dude someguy com  And the logs   Feb  6 09 17 11 myserver postfix qmgr 28875   E3B972264C  from  lt dude someguy com gt   size 459  nrcpt 2  queue active  Feb  6 09 17 11 myserver postfix smtp 21559   E3B972264C  to  lt me noone com gt   orig to  lt dude someguy com gt   relay myMTA x x x x  25  delay 1 1  delays 0 56 0 24 0 11 0 17  dsn 2 0 0  status sent  250 Ok 0000014b5f74a2c0-c06709f0-4e8d-4d7e-9abf-dbcea2bee2ea-000000    This is how it s working for me   Hope this helps someone
