I run pretty simple mail group distribution program that uses php/mysql
and the mail() function. I adapted it from an open source script. Most
of the time it runs well. But it does take a while to run through all
150 members of the list. So I'm half glad that I don't have a list of
1000 people or more.
Any way to optimize the mail function in terms of speed? Probably too
vague a question, sorry.
Have a look at the Swift Mailer package:
http://www.swiftmailer.org/
I use it to send out well over 1000 mails at a time and it works quite
fine for me. Check out the anti-flood extension for sending large batches:
$swift = new Swift(new Swift_Connection_SMTP('localhost'), 'domain.org');
/* 100 mails per batch with a 30 second pause between batches
*/
$swift->attachPlugin(new Swift_Plugin_AntiFlood(100, 30), 'anti-flood');
/* list of recipients is an object wrapping an array
*/
$recipients = new Swift_RecipientList();
$recipients->addTo('foo@xxxxxxx', 'foo bar');
/* headers
*/
$message = new Swift_Message('the subject');
$message->setCharset('utf-8');
$message->setReplyTo('reply@xxxxxxxxxx');
$message->setReturnPath('return@xxxxxxxxxx');
$message->headers->set('Errors-To', 'errors@xxxxxxxxxx');
/* multipart is a breeze
*/
$message->attach(new Swift_Message_Part($plain_content));
$message->attach(new Swift_Message_Part($html_content, 'text/html'));
/* if you're sending the mails from, eg. an admin page ...
*/
set_time_limit(0);
ignore_user_abort();
flush();
/* send it out
*/
$num_sent = $swift->batchSend($message, $recipients, new
Swift_Address('from@xxxxxxxxxx', 'from'));
This really should be rolled into the PEAR project, IMO.
