Yes, if you can stop mail server. Then kill the related process. No, otherwise. -Kittiwat - Original Message - From: Matthew Delmarter [EMAIL PROTECTED] To: Michael Stearne [EMAIL PROTECTED] Cc: PHP Mailing List [EMAIL PROTECTED] Sent: Tuesday, July 03, 2001 9:38 AM Subject: RE: [PHP] sending 5000+ emails - use PHP?

Re: [PHP] sending 5000+ emails - use PHP?
From: infoz [EMAIL PROTECTED] If all the messages were identical, we might be able to get some efficiency by sorting the list by domain name and batching them up with SMTP That's a very BAD idea. If you sort the mail by domain, you will flood the mail queue because normally, mail sent to hotmail or yahoo will need a repeated attempts before getting through. Better leave the email address randomized as they are. -Kittiwat -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

This is how they have achieved speedups in later versions - when processing a queue, it sorts by domain first, so that it can open a connection and send repeated emails, rather than open a separate connection for each mail to that domain.

Re: [PHP] sending 5000+ emails - use PHP?
Can't say that I agree. Once you get through to the SMTP port you can tell it that the following message is supposed to go to a list of people and you only connect once, vs. connecting once for each recipient. More efficient all the way around, I would think. Mind you, I haven't tried this on a large scale yet, so YMMV. - Tim If all the messages were identical, we might be able to get some efficiency by sorting the list by domain name and batching them up with SMTP That's a very BAD idea.

From: Henrik Hansen [EMAIL PROTECTED] strange but i heard otherwise, I heard that sorting by domain would speed up thing because the mailserver allready has a connection to the forign mailserver, what do you mean by repeated replies? OK, I got it partly wrong this time. What I supposed to mean is if you send mail with qmail (like we're using here) and if you sort outgoing bulk mail by domain, your mail server will try to connect to that busy remote domain with up to concurrency remote limit (in qmail) connections via multiple processes. That's, therefore, a bad thing for the remote site. These mail will then get queue in local mail queue, waiting for another attempt. And if that remote site is still busy, same thing will happen again in the next attempt. But with unsorted mail, these situation shouldn't be as bad becuase you won't use up the concurrency remote limit with a single busy destination. It may be a different story with sendmail. -Kittiwat -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

Re: [PHP] sending 5000+ emails - use PHP?
We use mail(). I have on my list to re-write it to use SMTP sometime to see if it works any faster, but it also goes into the if it ain't broke, don't fix it category. If all the messages were identical, we might be able to get some efficiency by sorting the list by domain name and batching them up with SMTP, but usually they're customized for each person. This gets run on a fairly beefy Sun E420 with an excellent network connection (Digital Island @ http://www.digitalisland.net) which may help things a bit. :) - Tim http://www.phptemplates.org Are you using the mail() function for this?

PHP can handle this (although you will definitely have to disable script timeout) in one run. But a smarter thing to do would be to not send all the 5000 emails at one time rather come up with a method that runs the PHP script every 5 minutes (a cron job) and send the newsletter out in 200+ email batches. This will reduce the load one the web server and also the mail server.
