mail() multiple Bcc at the same time

[Anon]

hey,

I'm trying to send one email with a lot of email adresses in the BCC line. It works fine with a few emails, but it won't work with the full DB.. 3000+ email adresses... am I stupid to even try this, is there a limit or something?

thanks

[guidance]

Most mailer will only relay less than 20 recipients include to, cc and bcc all together.
