bcc mass mailing

malcor

I have a php mail script that i use to send out a newsletter (html). the script loads all the email addresses as bcc but somehow after about 50 names the bcc addresses get written itno the body of the email! so much for anonimity! I tested this so many times and it looks fine to me (code below) anyone have any ideas why this would happen?

thanks
