Re: [PHP] Sending out large amounts of email
Hi, Our company is merging with another company and newsletter now needs to go out to more than 100.000 people. Out source it. It will cost you far less in the long run. And the short run. I tried Jango mail and they seemed OK, though I didn't have to talk to their support, and my use was very brief. These types of company will also have far more success in getting the emails delivered (and not flagged as spam). -- Richard Heyes HTML5 Canvas graphing for Firefox, Chrome, Opera and Safari: http://www.rgraph.net (Updated February 28th) -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

It is proberly caused by a limit set in Postfix as you wrote. If you're sending emails one by one in a mail() call there is no limit (one email per recipient) If you're trying to cc or bcc the email addresses, then there probably is a limit. You should also talk to your ISP and email admins to find out how to avoid ending up on a SPAM blacklist after sending out that many emails. You're likely to trigger more than one automatic listing with that many messages. Bob McConnell -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Sending out large amounts of email
I have been running some tests with PHP mail() function, PHPMailer and PEAR:Mail using 6000 mails at once. Here's a sumarry of some of the results: PHP mail() send out 6000 mails in 1.75 seconds. PHPMailer using PHP mail() send out 6000 mails in 1.87 seconds. PHPMailer using SMTP send out 6000 mails in 12 seconds (Error without succes). PEAR:Mail using PHP mail() send out 6000 mails in 20 seconds (Apache reached 100% during this time). Running several test on PHPMailer using SMTP failed completely with more than 1000 mails. Probably if you tried to send 1,000 in one smtp conversation. Postfix has a setting that will control this (as far as I remember anyway). You'll need to cycle the connection. - connect - send 100 - disconnect repeat. Everywhere on the net I read that sending out mail using PHP mail() is slow and it is a bad idea and that using some mail class with SMTP directly would be much better. I have tested the run my tests with Postfix as the SMTP. Depends on the situation. Sometimes using an smtp server is better. Some hosts only let you send 'x' emails an hour or even 'x' emails every 5 minutes so you have to pause between each email being sent so you don't flood their servers. If you're only using your server and your tests show php mail() works, then use it. PHPMailer comes in very handy when you have to do one or more of the following: - send multipart emails (html + text) - include attachments - embed html images in the content - possibly send to an smtp server All of that functionality is already built, works, tested etc - you don't need to do it all again. I have gotten the best results using PHP mail(). When the volume is belove 6000 PHP mail() is by far the fastest. What about 10,000? What is the best solution in real life dealing with huge amounts of mail? PHP mail() vs. some class using SMTP or binary sendmail (or wrapper)? mail() internally calls the wrapper, I doubt you'd see much of a difference there. -- Postgresql php tutorials http://www.designmagick.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Would someone mind sharing experience and perhaps shedding some light on this issue? What is the best solution in real life dealing with huge amounts of mail? PHP mail() vs. some class using SMTP or binary sendmail (or wrapper)? All insights would be appriciated. Best regards. Brian I've done a lot of work trying to get mail servers/php code to work reliably together in sending bulk mail. It's not trivial business. If you have control of the setup, change the mail server to just queue your mail instead of sending it directly. I did this and it solved a lot of really nasty headaches. I use Zend_Mail this method to send custom generated html emails to a lot of people and it never fails. It might not work for you though, so good luck! -- http://www.voom.me | EFnet: #voom -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
