Hi Adam,
Thanks for your posting.
The POP3 Connector supports both individual POP3 mailboxes and global POP3
mailboxes.
1. Individual POP3 Mailboxes - An individual mailbox is where e-mail for an
individual user account is stored in a single mailbox (e.g., any@xxxxxx).
This mail is then delivered to a defined user on the Exchange server.
2. Global POP3 Mailboxes - A global mailbox is where e-mail for an entire
domain is stored in a single mailbox (e.g., all e-mail addressed to @ms.com
is stored in a single account). When this mail is delivered to the Exchange
server, the user name defined to the left of the @ symbol must match a
defined Exchange user.
Some ISP's have the ability to setup a global mailbox. This is a single
mailbox that will accept all e-mail for @ms.com regardless of the alias.
When you configure the connector you can tell it that the mailbox is a
global and choose the e-mail domain (ms.com) that it will download e-mail
for.
When the connector downloads the e-mail it will parse the headers for the
e-mail for addresses with @ms.com, if it finds a match it will do an LDAP
query into the AD to try to find an identical match to the address. If that
matches succeeds then it will deliver the e-mail to that user. If it fails,
then it will deliver the e-mail to the undeliverable POP3 mailbox.
The Undeliverable POP3 Mail option won't work in the individual user
mailbox scenario. In this case, the POP3 connector doesn't have to look for
a destination for the e-mail. It knows that any e-mail in this mailbox goes
to this mailbox, so unless that mailbox has been deleted it will bypass the
undeliverable check and attempt CDO delivery of the e-mail. If the e-mail
fails during the CDO delivery stage then the POP3 connector doesn't care.
The undeliverable option only works if the POP3 connector can't find a
destination for the e-mail. If it finds a place to put the e-mail, it will
hand the e-mail off to CDO for delivery.
Hope this helps. If you have any questions please do not hesitate to let me
know.
