Fresh install of 24.7 on Ubuntu 22.04 using auto script Can't send mail

After a fresh install of 24.7 using the automated script from here:  https://docs.zextras.com/carbonio-ce/html/install/scenarios/single-server-scenario.html   I cannot send mail.  after pressing send i get "something went wrong" error and mail goes to draft folder.  Happens on every email sent and I cannot even send to myself. 

How do i correct this.  Done install 3 times and same issue
