I suddenly have a problem with a website that sends out an SMTP email on a contact request page.  This happens on occasion when I have an ISP issue with the email address i use.  AT&T uses a Secure Mail Key and when I am forced to change it, I have to go into Website X5 and update this password for sending an SMTP email.

It has been so long since I had to do this, I can't find the area where I make this change.  The Help function says to go to Settings and select Advanced and then Data management.

I  cant  find  that  anywhere!  When  I go  to  settings,  there  is  no  Advanced option  that  I can  see.
