Postfix relay problem

Asked by MarkWP in Post Office Protocol 3 (POP3), Email Servers, Simple Mail Transfer Protocol (SMTP)

Tags:

I am running CentOS with postfix, spamassin, dovecot using pop3 outlook clients.  A few days ago 2 of my users started having an issue sending mail to any address that is not in our strdetail.com domain.  They are able to send e-mail to users in the strdetail.com domain fine.  I should note that both of the users having problems are offsite users.
 
This is the error message
554 <israel_twinkle@yahoo.com>: Relay access denied

Nothing has changed in the e-mail server setup or the client setup.  
I have deleted the e-mail account and created a new one but it has the same problem.  
I have created a new account using a different e-mail address and it works fine.
I have checked to make sure that all clients are logging into the mail server before sending mail.

Please let me know if you need me to post any configuration files or other information.Start Free Trial
