I have a Dahua XVR5108 HS DVR. All is working fine with the exception of it sending Email alerts. I have entered all the Information, smtp, email Recieve & send. Password the lot. I keep getting Fail when i do hit test. I have also tried it on Yahoo mail account and outlook mail account with the same results. I know i have entered all the information correctly on all accounts as i have checked it over and over. I know i am missing something but can not figure out what.
