1. many providers will not accept email messages with horrendous amounts of BCC: entries (very spam indicative) 2. do not use mail() to do this 3. there are many excellent PHP mail classes (PHPClasses has a few and PHPMailer is an excellent alternative as well) 4. IM(H)O, if you are going to send out large amounts of mail, dump sendmail. QMail is much faster at SMTP.
Factors you may need to consider: If this is a newsletter, why not use something like ezmlm or majordomo? Are these individualized messages (custom inserts for names or email addresses, custom unsubscribes, etc.)? Many other programmers will mention things like having a dedicated outbound- SMTP machine, while fending the bounces and unsubscribes on another, hardware types (SCSI over IDE), etc. Make sure you have thought your application needs through before beginning programming.
