Support for BCC addresses in Narawen Inox POP3 Connector

Narawen Software — Fri, 23 Oct 2009 14:54:52 +0000

What is BCC address
When the sender of the e-mail message decides to hide recipients from being aware of each other he can use BCC (Blind Carbon Copy) address field while editing the message.

The e-mail addresses put in BCC field are not stored inside message header set like regular “To:” or “CC:” fields.

This can cause the situation that POP3 mailbox will contain message without any recipient addresses specified. It means that the recipient was on BCC list.

Static addressing is not affected
There is no issue with static addressing offered by Narawen Inox POP3 Connector. It just grabs all the contents of mailbox and sends to target address regardless if the messages have any addressing information or not.

How to fix dynamic addressing for BCC addresses
For dynamic addressing Narawen Inox POP3 Connector must have valid recipient address available in order to route the mail properly.
Starting from version 5.2 SR2 this is supported by handling “x-rcpt-to” header added by some mail servers with hint what was the recipient e-mail address.

We recommend the upgrade to latest release to avoid problems with dynamic addressing caused by BCC field.

How to stop Narawen Inox POP3 Connector from putting information events into event log?

Narawen Software — Wed, 28 May 2008 23:08:03 +0000

Select Log tab.
Select “Do not log detailed information events” option.
Click OK button to save the changes.
