Hello everyone,
I tried to configure sendmail so that I can use mail() in php. I don't host my email server, my ISP does. I just want to configure sendmail so that it uses external email server (my ISP) to send mail. When I executed mail(), i got no error report from php. I checked /var/log/maillog and it indicated that the message was accepted for delivery. However, it didn't delivery and indicated DSN: Service unavailable.
Can someone help or suggest any other way to get this thing works? I'm not in the position to setup and a fully function email server for this at this time. I just want to use my ISP email server for now. thank you so much for all your help.
Here is my /var/log/maillog and sendmail.mc
