You may even be sending solicited newsletter messages which are not SPAM, but for your ISP the load that it inflicts to the server is inacceptable. You may still use the server for sending SPAM, either many messages at once or one at a time. Either way, you should not be doing that unless your ISP authorizes you to do so. use bcc for the entire list of receivers. Also you cannot have a bcc without a to field anyway ...

Let me tell you a secret, for the SMTP protocol, whatever you put in the headers is irrelevant. Message headers are actually part of the message body for the SMTP protocol. So, you can put a fake To: header in there but the message is actually not delivered to it. What I mean is that SMTP servers do not parse headers. SPAM filters may do so and reject the message if you lack a wellformed To: header though. So, to please everybody, you can just put an arbitrary To: header and put all the real recipients in Bcc:. You need to check with the ISP if sending to many recipients respects the acceptable use policy. If they don't accept bulk mailing, it doesn't matter the method you use. I've never met an ISP that would refuse bulk mailing, as long as you can proove that you've got concent from the receivers for the messages. My mail server handles all the concent things itself, and sofar my ISPs have not complained about the up to 3 digit amounts of message that go out each day, with up to 4 digits coming in... So, there you have it, some ISP may allow a number of messages upto a limit but you need to ask them to know what the limit is. -- Regards, Manuel Lemos -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I guess that it's either harder on the server or because its most likely spam. You need to understand what the difference is.

[PHP] Multiple Addresses Mailer
Hi All I am creating a mailing list system in which I should be able to broadcast a message to multiple recipients I am using the mail() function and putting all the recipients names in the to argument separated by commas. When I do this the mail goes to all the people but they come to know that it was sent to others as well. I want to be able to send mail so that each recipient thinks that this mail was ONLY sent to him/her.

Re: [PHP] Multiple Addresses Mailer
The best solution would probably be to send each email by itself or do the actual sending thru a mailing list program. BCC works great, but a lot of spam filters will catch it - plus some shared servers have a limit on the number of BCC's on a single mail piece. olinux --- Rick Emery [EMAIL PROTECTED] wrote: Put all addressees in the BCC?? - Original Message - From: Pushpinder Singh Garcha [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Wednesday, October 30, 2002 1:47 PM Subject: [PHP] Multiple Addresses Mailer Hi All I am creating a mailing list system in which I should be able to broadcast a message to multiple recipients I am using the mail() function and putting all the recipients names in the to argument separated by commas.
