Has anyone been successful at using the above on a RHEL 6.2 environment? I am able to use Postfix using the php.ini SENDMAIL_PATH but when I bring down PostFix, start Apache James and switch the sendmail_path value to point to the Apache James 2.3.2 provided wrapper (/opt/james-2.3.2/bin/sendmail.py) the return code on mail() indicates it failed and no record of the wrapper being invoked. Calling the wrapper directly from the command-line works as expected so the problem is somewhere between PHP and the sendmail_path invocation. Thanks, Steve
