3.1 Agent Architecture

The GroupWise agents move email throughout your GroupWise system, as well as to and from the Internet.

The Post Office Agent (POA) runs for each post office. The POA delivers email to users’ mailboxes. The Message Transfer Agent (MTA) runs for each domain. The MTA transfers email between post offices and other domains.

The Internet Agent (GWIA) runs for at least one domain in your GroupWise system. The GWIA communicates with SMTP hosts across the Internet, sending and receiving email for users who are not part of your GroupWise system.

The Document Viewer Agent (DVA) runs for at least one post office. The DVA converts attached document files from a wide variety of formats into HTML format for indexing by the POA and for viewing in GroupWise WebAccess.
