I am receiving a similar error - 'User name or password is wrong'. I have logged into the email account and have verified the password. I am using a gmail account with port 465, smtp.gmail.com, with SSL enabled.
I am using a DS-2CD2032-I bullet cam.
I have successful ping of smtp.gmail.com and DNS and Default GW of camera is set to the router Default GW IP address.
Greatly appreciate any help in resolving this.
I have tried yahoo and outlook email addresses but failed for other reasons.
