I am about to release a classifieds website. Obviously if it gets a lot of traffic then it will handle a lot of email. Through c-panel I am using the Roundcube email program. Question - Do you know of a free or inexpensive email program that allows thousands (millions?) of emails to be sent a day? This would be needed for all the communications between customers. Do you have any advice? I put the email question here because I can't find a email category at DP. Thanks
You can design a newsletter or similar application. It will be easy to send email using script rather than email software or web mail. Also, if you are on dedicated/shared server , make sure your provider has no problem in sending millions of emails from their network. Kailash
If you are planning to write emailing script, make sure you use SMTP mailer other than mail() function as mail() will be way too slow and not capable of sending to large number of recipients. You can make use of free open source libraries like phpmailer. check this out: http://corpocrat.com/2009/07/06/php-emailer-script-using-mail-vs-smtp-which-is-best-method/ check this
