how can i make sendmail masquerade its sent emails from something other than nobody@localhost.localdomain?

basically, i have a php script on the same machine that is sending out emails to people with the wrong address.

please help!!!

look in sendmail.mc for "masquerade as"

thanks for replying,

checked the file, no "masquerade as" but i did find this line at the bottom of the file "Cwlocalhost.localdomain". could this be where it's getting localhost from?


DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')

don't you have that:

dnl #
dnl # The following example makes mail from this host and any additional
dnl # specified domains appear to be sent from mydomain.com
dnl #
MASQUERADE_AS(`domain.com')dnl

nope, nothing like that in my sendmail.mc file.

i using an rpm install (reports version as 4.0.4).

I don't know what to say then, else than putting in your file what i put in my last post and regenerate the sendmail.cf file
