The TCP/IP for VM IMAP Project (final beta version)
In an effort to exploit VM's strengths (reliability, availability,
and security) through networking, VM TCP/IP development undertook
an IMAP server project. Following a staged beta program, the IMAP
server is now included in the production level of TCP/IP for z/VM
4.2.0. The final version of the beta program (Beta Release 1.6.1)
will continue to be available for download as part of the
IMAP Beta program. This will allow
customers running on versions prior to z/VM 4.2.0 to try out the
TCP/IP IMAP server.
The VM IMAP server is written in IBM C for VM/ESA
and supports the IMAP protocol that is described in
RFC 2060. The server accepts mail from SMTP and
stores the mail in the IMAP mailstore (which is a dedicated SFS
filepool). The beta design uses the SMTPCMDS exit (which is
specified in the SMTP configuration file) to cause the SMTP virtual
machine to route all local mail to the IMAP server using the
spool. The IMAP virtual machine then uses the *SPL system
service to asynchronously read in the spool data and store
the mail in the mail store (if it was destined for a registered
IMAP user).
| | IMAP Status (Updated 10 Jan 2002) |
As previously mentioned, the final beta version of the
VM IMAP Server is currently available for download through
the IMAP Beta program.
Documentation on setting up and running the IMAP server is included in
the download package, and is also available from our VM IMAP Installation page.

Beta Release 1.6.1 of the VM IMAP Server is now available!
This is the final beta release of the IMAP server, as the server now
ships in the product as of release 4.2.0 of TCP/IP for z/VM.
It is important to note that the index structure used by beta releases
1.6 and 1.6.1 is not compatible with the index structure used
by earlier beta levels. Therefore, if you are migrating
from an IMAP beta release prior to 1.5, you must delete all users and
re-enroll them on the new beta release to force them to pick
up the new index structure. If you are migrating from
Beta Release 1.5, you can either delete and re-enroll all users or you
can use the IMAP5TO6 sample exec to convert their existing index
structures in the mailstore to the new format. Please note,
if you choose to change index formats by deleting and re-enrolling
users, all existing mail and folders will be lost.
