Have a problem with MLM. When I change the settings in im_prefs.php smtp authentication to match my account on the server I get a blank page when I test a subscribe or unsubscribe.
If I leave the smtp auth. setting to none both works fine, but I get a mail saying relaying not allowed when I test a subscribe or unsubscribe. I understand why I get this message, because my server needs authentication.
MLM runs on a mac os 10.4.11 server.
Any help would be great.
Thanks in advance
