[jira] [Commented] (OFBIZ-3379) Email sending process using one connection for To/CC/BCC causing issues

["elan (Commented) (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OFBIZ-3379?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13122564#comment-13122564 ] 

elan commented on OFBIZ-3379:
-----------------------------

# handle BCC via another connection
In RFC, the BCC shall be handled at MX (SMTP server). SMTP server will remove the BCC header while deliver the mail.
As a client, it has no need to handle BCC via another connection. 
# failure notification
SMTP server will send failure message to client, client shall notice the sender/from . 
But for sender/from , BCC is not secret, so it will be sufficiently to handle it the same as TO/CC .

> Typically BCCs are handled via the sending mail client. That is, when the client sees a BCC in an email, it will open up two connections to the mail server, the first for the To/CC fields, the second for BCC fields, this way the addresses are masked from the headers and there is that layer of anonymity that BCC is used for.
> What appears to be happening is that OFBiz is sending all of the information in one connection to the mail server and having the mail server sort out the details. So when sendTo encountering an invalid email, and then terminating the remaining execution of the outgoing process and no email sent to BCC address which is usually going to be a valid address from email settings for the company.
> To fix the issue, we need to send this via two connection to mail client.
