You can solve this (mostly) in admin-space by setting the sendmail_path, creatively, in php.ini. For example, I can send mail with this: sean@sarcasm:~$ php -d "sendmail_path=/home/sean/bin/mailwrap uniquehosthere" -r 'mail("sean", "subject", "message body here");' Here's /home/sean/bin/mailwrap: (echo "X-host-tag: $1" ; cat -) | /usr/sbin/sendmail -t -i And here's the resulting mail: From sean@sarcasm Mon Feb 19 11:54:22 2007 X-Original-To: sean X-host-tag: uniquehosthere To: sean@sarcasm Subject: subject Date: Mon, 19 Feb 2007 11:54:22 -0500 (EST) From: sean@sarcasm (Sean) message body here ... I'm not shooting down your idea, but there _is_ a way to solve this right away. (Perhaps I'm missing something obvious, but I don't see an obvious way to get around this tag in userspace.) The sendmail_path value could be set with php_admin_value in your VirtualHost config. S
