Sending BCC emails using a SMTP server?
- by Alix Axel
I've had this noted down on some of my code for a while:
/**
* Add a BCC.
*
* Note that according to the conventions of the SMTP protocol all
* addresses, including BCC addresses, are included in every email as it
* is sent over the Internet. The BCC addresses are stripped off blind
* copy email only at the destination email server.
*
* @param string $email
* @param string $name
* @return object Email
*/
I don't remember where I got it from but that shouldn't be relevant to this question. Basically, whenever I try to send an email with BCCs via SMTP the BCC addresses are not hidden - I've read the whole RFC for the SMTP protocol (a couple years ago) and I don't think I'm missing anything.
The strange thing is, if I send an email with BCCs using the built-in mail() function everything works just right and I've no idea why - I would like to roll my own email sender but I fail to understand this.
Can someone please shed some light into this dark subject?
