Global settings - email settings
From the home page, go to Configuration > Global settings > Email Settings:

The Email Settings page enables you to perform the following actions:
- Email "From" Address: enter or alter the Name, Email address and Company information from which you email advertisers.
- Email log: check this box to log all outgoing email messages.
- Email headers: anything entered in this field will appear as a header on each email message sent by OpenX.
- qmail patch: check the box to enable the qmail patch. This setting prevents a known bug in qmail which causes emails sent by OpenX to show their headers within the body text of the email.
