I'm trying to get a PHP mailing script (using PEAR) working on my web server connecting to my remote Postfix box, and each time the script executes, I get no errors in either my PHP output or my Postfix logs, but no email is sent.
The corresponding log items for the request are this:
Nov 19 10:15:34 mailer postfix/smtpd[2611]: connect from xxx-xxx-xxx-xxx.static.cloud-ips.com[xxx.xxx.xxx.xxx]
Nov 19 10:15:34 mailer postfix/smtpd[2611]: disconnect from xxx-xxx-xxx-xxx.static.cloud-ips.com[xxx.xxx.xxx.xxx]
I know my Postfix server is working correctly, since I have other applications that can send mail to it just fine (and they're relayed correctly).
I also know that this script is working since I can copy it verbatim (except for changing the location of the PEAR libraries) to another web server (on HostGator) and it connects and sends the email fine.
I wish I could get some sort of error message to give me some kinda clue as to where to go from here, but I've got no error messages: just a connection followed by an immediate disconnection. I am only having this problem trying to send mail from this specific web server.
What's causing this and what can I do to fix it?
The Web Server I'm having issues with is running Ubuntu 8.04.2 LTS (hardy).

tcpdump -s0 -X -i eth0 port 25 and host YOUR_CLIENTPHP_IP_HERE
Mind pasting a tcpdump trace here?
tcpdump -s0 -X -i eth0 port 25
Have you verified that php is configured correctly on the misbehaving server? i.e., are there additional restrictions set in php.ini that are different on the "bad" server versus the "good" one?
Sorry, my php-fu is weak, but if those are the only logs you're getting from postfix, my impression is that the problem is on the sending side, not the receiving one.
Failing that, I would loosen your smtpd_recipient_restrictions to see if that's not causing issues.
I think that specific webserver might have a host resolution issue. Perhaps you put the destination IP address in
/etc/hosts..? Or there is a MX caching issue..?If it works on a different server it's not a code problem. The tcpdump seems to show that the mail gets accepted. Check the mailer log.
If you are using cloud provider, then sometimes they are blocking outgoing SMTP traffic or limit number of outgoing connections and emails. Usually you need to submit request to remove mail limit and create reverse DNS record for your IP to domain mapping.
