PHP mail issue with www-data

Question

I am trying to invoke sendmail via PHP\'s mail function by the following code:

$to      = \'blah@email.state.edu\';
    $subject = \'test\';
    $message = \         


        

Answer 1

Although this is an old question, I'm adding this answer in case it is of help to someone:

I had the same problem with the From: header being re-written to www-data@host... I eventually tracked it down to the ssmtp bridge service that was piping mail from our web server into our mailserver. I added the line FromLineOverride=YES in the file /etc/ssmtp/ssmtp.conf and the problem disappeared.
