Sendmail not working in cent OS 4.6
 

Hello Linux gurus,

I am new to sendmail, I had configured my php to use sendmail as its mail agent. My server which is centOS 4.6 in this case runs in a lan.

What I need is that when i fire a mail function from php page hosted on my server in LAN, mail should get delivered to gmail or whatever destination address is..

But I am facing problem...When I open my php page which fires the mail, it takes long time to load say 1-2 minute in loading. After that it says Message sent successfully, but message not get delivered.

I had checked sendmail it is running...
I also checked spam folder of destination email..
sadly, I am unable to do it....

Please Help Me.....

However it shows that mail is accepted for delivery, but i did not get any mail...anu pointer, where the error could be...

Hi,

Mail is not accepted for delivery. It's stuck in queue. You can check the queue with:
This can happen for various reasons:
Usually your isp blocks outgoing traffic to port 25 (you should use your isp mail server as a smarthost)
Other reasons could be: a bad dns server, the queurunner that is not running
Try from your box to telnet directly gmail and see if port 25 is blocked:
