ERROR: Message not sent. Server replied:Authentication failed 535 Incorrect

[pratapsingh]

I got this error while sending mail . I am able to login to my mail. I am receiving mails from outside and i read them also. But I am not able to send mail from my mail. What could be the reason for
"ERROR:
Message not sent. Server replied:

Authentication failed
535 Incorrect authentication data"

Note :- Recently i took the backup of my server through cPanel and deleted my website from the server through WHM and after that I restored it. I think due to that it's happening.


My error log is
2009-03-25 15:00:25 fixed_login authenticator failed for localhost (server.com) [127.0.0.1]: 535 Incorrect authentication data (set_id=user@xyz.com)

hey,
try this
cPanel Forums

[pratapsingh]

i have posted this issue there also .. thanks for info ..

[davidanand]

hey click on the link I have mentioned there is the answer for the error

[pratapsingh]

Hey thanks man it worked ...

Solution is
"The logs were showing same error 535 Incorrect authentication data. After digging around I finally found that this domain was listed in /etc/demodomains and the user was listed in /etc/demousers. I disabled the demo mode from WHM and the account can now authenticate without any problems. Hopefully this helps."
