The configuration of the IMAP server is discussed in the PMDF Installation Guide. Refer to that manual for directions on configuring the IMAP server.
The MessageStore IMAP server is a high-performance, multi-threaded server which serves out MessageStore accounts. The MessageStore stores pre-computed responses to many IMAP queries at delivery time so that the IMAP server has much less work to do.
The IMAP server uses PMDF's authentication services and as such supports plain text passwords as well as APOP
, CRAM-MD5
and DIGEST-MD5
authentication. Additionally, the server supports SASL (RFC 2222). For
further information on the POP3 server or authentication services,
consult the "Connection Authentication and Password
Management" chapter of the PMDF System Manager's Guide.
11.3 poppassd Server
Poppassd
is an ad hoc protocol for changing POP, IMAP, and native
account passwords. This protocol is used by several clients such as
Eudora and Mulberry. PMDF provides a poppassd server which can be used
by clients to change their password. The server is configured as part
of the POP3 and IMAP server configuration process. Consult the PMDF
Installation Guide for details on configuring the POP3 and IMAP
servers.
Note that under the poppassd
protocol, plain text passwords are exchanged in the clear between the client and poppassd server --- even when the client is otherwise using APOP
, CRAM-MD5
, or DIGEST-MD5
for authentication. Owing to this limitation of poppassd, its usage should be questioned in settings where APOP
, CRAM-MD5
, DIGEST-MD5
or similar password security is expected.
11.4 HTTP Server
The PMDF HTTP server is configured as part of the PMDF MTA
configuration. See the PMDF Installation Guide for details.
The HTTP server provides the web-based management interfaces for both
the popstore and MessageStore as described in Chapter 4.
