How to: Use the POP3 adapter
 
Problem: We have an email box that receives order from different customers in different formats. These orders also need to be processed in different manners.
We needed an adapter that could receive these emails, and add a custom pipeline component to it to Extract the attachments (also see How to: Extract email attachements using a custom pipeline component).
 
The post Office Protocol 3 adapter is to retrieve data from a server that houses POP3 mailboxes into a running Microsoft BizTalk Server by means of the POP3 protocol.
The POP3 adapter consists of only one adapter. The receive adapter controls the recieve location that uses the POP3 adapter.

The POP3 receive adapter retreives email from specified mailbox on a specified server.
It does not support batching.
The POP3 adapter enables you to move data from a POP3-enabled mailbox to BizTalk Server.
- Pulling files from the POP3 server mailbox on demand,
- Running Polls based on a configurable schedule, 
- Specifying the POP3 server mailbox as an IP address or host name, port, username and password.
- Implicit MIME processing (Multi-purpose Internet Mail Extension: Extension of the origional internet email protocol to exchange different types of datafiles like audio, video img files etcetera).
The adapter can decrypt digitally encrypted emails; set the ' Apply mime decoding' to true for receive locations that use the POP3 adapter.
Supports receiving messages up to 50 mb in size.
