- | When VPOP3 is configured to download mail from a shared (catch-all) POP3 mailbox at your ISP, it has to read through the standard message header lines to see who the message is for. It looks at the To, Cc, Received, Apparently-To, | + | |

- | In most cases this will work fine. However, if the message has been BCCd to you, the recipient address will not be in the message header at all (that is the whole point of BCCd mail). The message reaches your ISP mailbox because the actual recipient is listed in the **SMTP Envelope** but most ISPs will throw that information away when they deliver the message into a POP3 mailbox. Because of this there is no automatic way that VPOP3 can work out the message' | + | |

- | + | ||
- | Some ISP will copy the SMTP Envelope recipient information into custom header fields in the message, such as **X-RCPT-TO** or **Delivered-To**. In this case, you can tell VPOP3 to use this header information (see the **Custom Headers** section below). | + | |
- | + | ||
- | If your ISP does not copy the SMTP Envelope information into the header your options are limited: | + | |
- | * Manually. An administrator can go through the messages which were not delivered, and forward them to the appropriate person. | + | |
- | * Mappings. Many BCCd messages are actually from mailing lists. In this case the **To** header will often have the address of the mailing list in it. In this case you can create a **Mapping** of type **POP3** from the mailing list address to the user(s) who want to receive the message. | + | |
- | * [[Incoming SMTP Feed|SMTP Feed]]. If you can switch to an incoming SMTP Feed for your mail (instead of POP3 collection), | + | |
