IMAP4 is an Internet Protocol (IP) for remote mailbox access; its specifications
are documented in RFC 2060 (for more information, see RFC 2060—Internet
Message Access Protocol - version 4rev1).
Initially, the server host starts the IMAP4 service by monitoring TCP port 143.
When a client host establishes a TCP connection with the server host, the
IMAP4 server sends a greeting. The client and IMAP4 server then exchange
commands and responses until the connection is closed or aborted.
10.1.8 ZLE Mail Adaptor
A ZLE Adaptor is provided to email enable applications. Applications can send
email messages to internet users via the ZLE Adaptor. The Adaptor can be
invoked by applications on the platform as well as applications off the platform.
The adaptor supports a simple input buffer. Applications on the NonStop™
platform can invoke the ZLE Adaptor via a simple server class send.
Applications from an NT or UNIX platform can invoke the adaptor using a
socket interface.
10.1.9 OmniMessaging Application Manager
The OmniMessaging Application Manager receives requests from users,
currently via the Java Administrator client, to monitor various performance
indicators of OmniMessaging resources and to query the system configuration.
This interface is also used to start and stop traces for troubleshooting and to
turn accounting events on or off.
The Application Manager has the capability to display statistical information
relating the to live OmniMessaging environment. During the lifetime of each
server process, statistical information is accumulated within the server’s
memory as each new message is processed. The information gathered varies
depending on each server class – the following is a summary of statistical
information provided by the main servers:
POP and IMAP servers:
• # of openers
• # of current sessions
• # of connections accepted
• # of connections rejected
• Shortest connect time
• Longest connect time
• # of invalid commands
• # of messages sent
• # of messages deleted
• Size of largest message
• Size of smallest message
