Send Pipelines
Outgoing messages can also go through multiple stages, as defined by a send pipeline. The following figure shows the stages and standard components for a send pipeline.

The stages and their associated components are:
- Pre-assemble. Provides no standard components. Custom components can be inserted here as needed.
- Assemble. Paralleling the Disassemble stage in a receive pipeline, this stage also has three standard components:
- Flat file assembler. Converts an XML message into a positional or delimited flat file.
- XML assembler. Enables adding an envelope and making other changes to an outgoing XML message.
- BizTalk Framework assembler. Packages messages for reliable transmission by using the BizTalk Framework messaging technology.
- Encode. BizTalk Server 2004 provides one standard component for this stage, the MIME/SMIME encoder. This component packages outgoing messages in either MIME or S/MIME format. If S/MIME is used, the message can also be digitally signed and encrypted.
