The Internet Agent (GWIA) provides communication between GroupWise users and users of other messaging systems who send email across the Internet. The GWIA picks up inbound email messages from the Internet, converts them from MIME format to the GroupWise message format, and then passes the converted messages to the GroupWise Message Transfer Agent (MTA).
For outgoing messages to the Internet, the MTA passes the messages to the GWIA, which then converts the messages to Internet messaging format, and then sends them to the designated Internet addresses.
