How to solve authentication error in sendmail relay through gmail

Question

I followed the steps in http://www.linuxha.com/other/sendmail/gmail.html to setup gmail in send mail. But when I try to send mail I got the authentication failure message.

—– Transcript of session follows —– … while talking to smtp.gmail.com:

AUTH dialogue <<< 535-5.7.1 Username and Password not accepted. Learn more at <<>> MAIL From: SIZE=538 AUTH= <<< 530-5.5.1 Authentication Required. Learn more at <<< 530 5.5.1 http://mail.google.com/support/bin/answer.py?answer=14257 i7sm28108408qap.12 554 5.0.0 Service unavailable

Solution

Do you have the correct (gmail) username and password settings in client-info? If yes, is sendmail able to read this file? Have you built your new sendmail.cf after editing sendmail.mc? Have you restarted sendmail afterwards?

That code above doesn't seem to have any authentication information, that is what the Gmail server is complaining about.

[Arul]

@Tim /etc/mail/authinfo file have the gmail login information..

[Arul]

Yes I have correct username and password in /etc/mail/authinfo. I can login with this info in browser. I build successfully sendmail.cf using "make all install restart" After done everything sendmail is successfully restarted.

Permissions like I said. Is sendmail able to read the external files? Look for warnings in the log files.

[Arul]

Yes It can read external file.. sendmail 14165 root 3u IPv4 517170 TCP *:smtp (LISTEN) Its started by root user.. -rw------- 1 root root 180 Dec 29 06:40 authinfo That authentication file have read and write access for root user

Now is working.. A small typo in my password.. :( Thanks to all
