note 66981 added to ref.mail

is there another (better) way as alternative for sending the mails to a great number of recipients (5k+ newsletters) step by step in a loop? is it a good solution to send it all-in-one (through my own smtp server) by simply write all mail adresses as BCC? or are there filters or any other troubles waiting for me? what else would be a good solution to make the send process perhaps a bit speeding up (with reference to the script runtime, no matter how long it takes for sending out in reality, but the script should quickly be ready. so there would not be great danger of canceling the process while it is not ready. else this would have the result of some users who got the mail, other ones did not get it!) thank You for advice ---- Server IP: 212.124.37.9 Probable Submitter: 84.155.238.40 ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/ref.mail.php Edit -- http://master.php.net/note/edit/66981 Del: integrated -- http://master.php.net/note/delete/66981/integrated Del: useless -- http://master.php.net/note/delete/66981/useless Del: bad code -- http://master.php.net/note/delete/66981/bad+code Del: spam -- http://master.php.net/note/delete/66981/spam Del: non-english -- http://master.php.net/note/delete/66981/non-english Del: in docs -- http://master.php.net/note/delete/66981/in+docs Del: other reasons-- http://master.php.net/note/delete/66981 Reject -- http://master.php.net/note/reject/66981 Search -- http://master.php.net/manage/user-notes.php
