PHP sendmail messages disappear

This is continuation of another question asked a couple of days ago. I was originally getting errors when trying to submit from a contact form. As suggested by one of the experts I installed postfix on the Ubuntu 10.04 server and I stopped getting the error page. Now after modifying the php.ini file for apache as suggested I still don't receive any messages. I uncommented the Unix sendmail line and added the path to sendmail with the -t and -i flags but I still don't get any messages or errors. I also checked the mail.err file and don't see any errors.

There aren't any errors, but does the log mail.log show that the emails are being received in postfix from php?

Second question: can your server resolve the mx records for any given destination email address? E.g.: dig mx hotmail.com show any results that locate the mx records?

Third question: is your server allowed to connect on outbound servers on the 25 port in order to deliver mails?

Right after postfix install I see where I received the messages in the var/mail directory, but didn't get to my real mail server. That was before I modified the php.ini. I have since reverted the php and don't see any change.

Dig pulls up correct dns info.

I can connect to my real mail server from the webserver on port 25. They are on the same subnet.

Can you dig dns records for the destination email address? If you can, it means something is still incorrect on php.

You say you have received some messages in /var/mail.  Can you look at them to see what's in there?  There may be some bounce messages that can point to the solution.  If so, post what the errors are.

It ended up being the domain I chose to send the mail to in the contactengine script and when setting up postfix (I have them set the same.) In the future I will make sure to choose a different domain than the one I am sending to. The web server isn't going to be used as a mail server other than php functions. I guess I need to make sure I shore the sucker up now to make sure it's not abused by spammers.

TRW, I didn't see any bounce messages just the ones I submitted from the contact form on the site.
