For the past few days I have been chasing a reported issue where Email Users is putting recipient addresses into the CC header instead of the BCC header. This has been a challenge to chase down. To assist in this I have add a bunch of new debug and checking to Email Users.
Email Users will now check and report if wp_mail() has been overloaded by a plugin or theme. Since wp_mail() is a pluggable function, this is the one area which is really out of the control of Email Users. Simply knowing if wp_mail() has been overloaded is very helpful.
Additionally, I have finally found a way to initiate a complete email which is aborted just prior to the email actually being sent. The content of several internal structures is displayed on the Dashboard so the email headers can easily be examined.
This build is in DEBUG mode which means it will never actually send an email unless wp_mail() has been overloaded in which case all bets are off. Please visit the Settings page first to determine if wp_mail() has been overloaded. If it has, do not send any email but let me know which plugin or theme has overloaded wp_mail().Email Users Beta (176 downloads)
