Ok… I created 17 different email addresses for 17 different forums with the same password.
I put the email address in every single forum under forum management and saved.
I went to email options, put in the password, and set my gmail settings as follows:
smtp.gmail.com
port 465
Password
Use SSL is checked.
I am not able to complete test authentication. I also have this pink box:
Your PHP installation does not include the IMAP library which means post-by-email can not try to retrieve attachments from emails and any attachments may cause the post to fail
thanks guys
