add_bcc_recipient
Mask-K opened this issue · 8 comments
so I'm trying to send a message to several users like this:
msg->add_bcc_recipient(mailio::mail_address("Customer", recipient1));
msg->add_bcc_recipient(mailio::mail_address("Customer", recipient2));
but the problem is that recipients can see each others email addresses. Checked on gmail and outlook
Let me debug it.
I am not able to reproduce it. Can you please give me the full example with the mangled sensitive data?
auto msg = std::make_shared<mailio::message>();
msg->header_codec(mailio::message::header_codec_t::BASE64);
msg->from(mailio::mail_address("My name", m_config->smtp->email));
msg->content_transfer_encoding(mailio::mime::content_transfer_encoding_t::QUOTED_PRINTABLE);
msg->content_type(mailio::message::media_type_t::TEXT, "html", "utf-8");
msg->add_bcc_recipient(mailio::mail_address("Customer", "mail1@gmail.com"));
msg->add_bcc_recipient(mailio::mail_address("Customer", "mail2@gmail.com"));
msg->add_bcc_recipient(mailio::mail_address("Customer", "mail3@gmail.com"));
msg->subject("New goods in the store!");
msg->content("");
m_connection->submit(*msg);
I think mailio could be changed in that way, but I believe it would be against the specification. I will check for that, also I am not sure whether the undisclosed-recipients
is specified.
The RFC 5322/3.6.3 allows that the Bcc users see their own addresses in the Bcc field (others are hidden of course). The To and Cc recipients remain where they are. Is it acceptable to you?
Fixed with the PR.
