When a new user registers on my board, they do not receive the activation link. However I can mass e-mail users from the ACP with no problem.
Any suggestions. Here are the relevant settings:
Account activation: By User
Enable board-wide e-mails: Enabled
Users send e-mail via board: Enabled
E-mail function name: mail
Contact e-mail address: firstname.lastname@example.org
Return e-mail address: email@example.com
Use SMTP server for e-mail: No
I found it and it is really STUPID.
You MUST change the permissions for Newly Registered Users group to "Can send emails = yes" in order for the activation link to be sent. Pretty lame but that fixed it.
