Question

I originally posted this at the Amazon SES forums here: https://forums.aws.amazon.com/thread.jspa?threadID=74561&tstart=0

But since the stackoverflow community is more active, I’ll post it here 🙂

Basically I have a forecah loop around a cURL post (see bottom of post for script snippet). It works for a couple hundred posts, but then starts to fail for all the others. Here’s the last successful post followed by the first of 100’s of unsuccessful posts…

The the failures start….

Here’s the script snippet

foreach($JSONarray['DATABASE'] as $E) 
{
         if ((array_diff($E['LISTS'], $FILTER) != $E['LISTS']) && $E['STATUS'] == "CONF")
         {
         $MAIL = "Action=SendEmail&Source=".$FROME."&ReturnPath=".$BOUNCE."&Destination.ToAddresses.member.1=".$TOE."&Message.Subject.Data=".$SUBE."&Message.Body.Html.Data=".$BODYE;           
         //curl
         $aws = curl_init();
         curl_setopt($aws, CURLOPT_POSTFIELDS, $MAIL);
         curl_setopt($aws, CURLOPT_HTTPHEADER, $headers);
         curl_setopt($aws, CURLOPT_HEADER, false);
         curl_setopt($aws, CURLOPT_URL, $url);
         curl_setopt($aws, CURLOPT_RETURNTRANSFER, true);
         curl_setopt($aws, CURLOPT_VERBOSE, true);
         curl_setopt($aws, CURLOPT_STDERR, $SESLOG);
         curl_exec($aws);
         curl_close($aws);
         }
}

Any ideas?

I figured out the problem:

<ErrorResponse xmlns="http://ses.amazonaws.com/doc/2010-12-01/">
<Error>
<Type>Sender</Type>
<Code>RequestExpired</Code>
<Message>Request timestamp: Mon, 22 Aug 2011 15:49:11 UTC expired.  It must be within 300   secs/ of server time.</Message>
</Error>
<RequestId>0e3899cb-ccd7-11e0-9f09-c5d12d442026</RequestId>
</ErrorResponse>

My headers were set-up outside the forecah loop around curl. Doh! So I just moved that bit of code into the loop to solve the time-out problem.
