I'm the system administrator but haven't really checked the config since i didn't know this type of email sending was considered relaying. > If your "working mail program" is Outlook then it is using MAPI not > SMTP to send/receive email. Yep we're using Outlook I actually need this to send out an email to all our customers with greetings for the holidays. Last year they manually sent out batches and i said Python probably would make it easy to send the emails around. Should have shut up, hehe :) So my best bet is to allow relaying for the period of the test and then disallow it again? Regards, Benedict -- http://mail.python.org/mailman/listinfo/python-list
