PHPMailer Issues

[sorathia]

I seem to be having weird issues with PHPMailer. I'm hoping someone can point me in the right direction...

I currently have VPS hosting.

I have a reservation system that sends out multiple emails after a ride is booked. 1 email to customer, 1 email to limo company, 1 email to a backup system, & 1 for text message alert

95% of the time, all of the emails go out successfully

5% (or less) some of the emails are not going out. For example, out of the 4 emails that's supposed to go out, 3 would go out and 1 would not.

All the emails are being sent from 1 PHP file. Here is the Command used to send off 1 of the 4 emails:

$sent = mail($to, $subject, $message, $headers) ;

Rest of the emails are being sent using the same command.

Anyone else experience this? Are there any settings in PHPMailer that I could check?

Thanks for any help anyone can provide!

put a sleep command in between each of the mail lines

like:

$sent = mail($to, $subject, $message, $headers) ;
sleep(5);
$sent = mail($to, $subject, $message, $headers) ;

Even on VPS your probably triggering Exims spam detection rule and it just starts dropping emails till you stop.

The sleep command will cause php to wait the specified number of seconds...

Thanks

Its the number of messages sent in a x time period that triggers this and once triggered till you stop it won't send mail out.

Your best to NOT change this as it just leads to your mail server getting blacklisted and once your on these lists.. most don't remove IP's or servers with out a lot of hassle.

Change your script to not send out as many emails that trigger this.

Thanks rec9140 for your help!
I will add a sleep command to see if that fixes it.

I don't think there is such a limit in Exim default configuration.
And the link you give is talking about totally different situations.


sorathia,
do you have cPanel/WHM in your VPS?

quietFinn, Yes, I do have both cpanel and WHM access.

Is there anything I should check?

Thanks

Go to http://www.configserver.com/cp/cmq.html and download and install their ConfigServer Mail Queues (cmq).
That's the easiest way to check if your emails are actually in Exim's queue.

You can use:

exim -bpc #total emails in queque
exim -bp | exiqsumm #report about emails in queque
