Is there any practical or policy limit on the number of addresses that can be included in a Bcc: header in a call to sendmail?
I have a mailing list of ~1300 addresses in a MySQL database that I want to e-mail from a PHP script. I have figured out how to invoke sendmail from the script.
I don’t want to loop 1300 times through the call to sendmail, because the PHP interpreter could time out. It seems like a logical notion to put all the addresses in the Bcc header.
Will this work? Is it a problem for any reason?
