Note Submitter: Scott Fletcher ---- This is for any Unix or Linux machine using the Sendmail. However, no guarentee that it would work in Windows. Some SMTP won't accept e-mail with the "From: host@domain" without the suffix "com", like "domain.com", so using the "From: host@domain.com" option in the $header does not solve the problem for me. Someone suggest using the php.ini with the configuration by adding the "-f user@domain.com" to the sendmail path. Example look like this.... --clip-- sendmail_path = /usr/sbin/sendmail -t -i -f user@domain.com --clip-- This is not an option for me because it is limit to one user, not more than one. So, Finally there is a workaround to the problem and it is very simple.... Just add this entrie to the /etc/hosts file in Unix or Linux. Just substitute the word in bracket for a value.... --clip-- <ip address> <machine's_host.domain.com> --clip-- Example ... --clip-- 123.456.789.012 xyz.abc.com --clip-- Make sure your machine do the search order with the host first before the DNS or Nameserver. In my case in AIX, is "/etc/netsvc.conf". Hope Make sure your machine is set to read the host file first before the DNS or the nameserver, if not then make some changes to it. In my case for AIX, it is "/etc/netsvc.conf"... Hope this help....
