General Questions • POSTFIX, problems using SMTP authenticacion.

Hello,

We are using postfix without authenticacion and works correctly, but my company now requires smtp user/password.

I have configurated password file in /etc/postfix/sasl_passwd

[smtp.domain1.com]:1025 app1@emaildomain.com:password

Is the username on your relay server exactly "app1@emaildomain.com"?
Did you create the hash db with 'postmap /etc/postfix/sasl_passwd' ?
Can you send mail using those credentials with a regular mail client?

When i try to send email i got this message on log: (Host or domain name not found. Name service error for name=emaildomain.com type=A: Host found but no data record of requested type)

Which server generated that message?
It would be easier to post the actual log snippet rather than paraphrasing.

I have asked the mail department if the user is that or has another name, I will test after that with a smtp client from windows and if it works I will start with the postfix configuration

yes, I have created the database with > sudo postmap /etc/postfix/sasl_passwd

Im using postfix to send message from a nagios server, the error message appears in the log /var/log/mail.log of this server

thanks for the help, I will let you know
