SYNOPSIS

         use IMAP::Admin;

         $imap = IMAP::Admin->new('Server' => 'name.of.server.com',
                                  'Login' => 'login_of_imap_administrator',
                                  'Password' => 'password_of_imap_adminstrator',
                                  'Port' => port# (143 is default),
                                  'Separator' => ".", # default is a period
                                  'CRAM' => 1, # off by default, can be 0,1,2
                                  'SSL' => 1, # off by default
                                  # and any of the SSL_ options from IO::Socket::SSL

DESCRIPTION

       IMAP::Admin provides basic IMAP server adminstration.  It provides functions for creating
       and deleting mailboxes and setting various information such as quotas and access rights.

       It's interface should, in theory, work with any RFC compliant IMAP server, but I currently
       have only tested it against Carnegie Mellon University's Cyrus IMAP and Mirapoint's IMAP
       servers.  It does a CAPABILITY check for specific extensions to see if they are supported.

       Operationally it opens a socket connection to the IMAP server and logs in with the
       supplied login and password.  You then can call any of the functions to perform their
       associated operation.

       Separator on the new call is the hiearchical separator used by the imap server.  It is
       defaulted to a period ("/" might be another popular one).

       CRAM on the new call will attempt to use CRAM-MD5 as the login type of choice.  A value of
       0 means off, 1 means on, 2 means on with fallback to login.  *Note* this options requires
       these perl modules: Digest::MD5, Digest::HMAC, MIME::Base64

       SSL on the new call will attempt to make an SSL connection to the imap server.  It does
       not fallback to a regular connection if it fails.  It is off by default.  IO::Socket::SSL
       requires a ca certificate, a client certificate, and a client private key. By default
       these are in current_directory/certs, respectively named ca-cert.pem, client-cert.pem, and
       client-key.pem.  The location of this can be overridden by setting SSL_ca_file,
       SSL_cert_file, and SSL_key_file (you'll probably want to also set SSL_ca_path).

       If you start the name of the server with a / instead of using tcp/ip it'll attempt to use
       a unix socket.

       I generated my ca cert and ca key with openssl:
        openssl req -x509 -newkey rsa:1024 -keyout ca-key.pem -out ca-cert.pem

       I generated my client key and cert with openssl:
        openssl req -new -newkey rsa:1024 -keyout client-key.pem -out req.pem -nodes
        openssl x509 -CA ca-cert.pem -CAkey ca-key.pem -req -in req.pem -out client-cert.pem
       -addtrust clientAuth -days 600

       Setting up SSL Cyrus IMAP v 2.x (completely unofficial, but it worked for me)
        add these to your /etc/imapd.conf (remember to change /usr/local/cyrus/tls to wherever
       yours is)
         tls_ca_path: /usr/local/cyrus/tls
         tls_ca_file: /usr/local/cyrus/tls/ca-cert.pem
         tls_key_file: /usr/local/cyrus/tls/serv-key.pem
         tls_cert_file: /usr/local/cyrus/tls/serv-cert.pem

       For my server key I used a self signed certificate:
        openssl req -x509 -newkey rsa:1024 -keyout serv-key.pem -out serv-cert.pem -nodes
       -extensions usr_cert (in openssl.cnf I have nsCertType set to server)

       I also added this to my /etc/cyrus.conf, it shouldn't strictly be necessary as clients
       that are RFC2595 compliant can issue a STARTTLS to initiate the secure layer, but
       currently IMAP::Admin doesn't issue this command (in SERVICES section):
         imap2  cmd="imapd -s" listen="simap" prefork=0

       where simap in /etc/services is:
         simap  993/tcp   # IMAP over SSL

   MAILBOX FUNCTIONS
       RFC2060 commands.  These should work with any RFC2060 compliant IMAP mail servers.

       create makes new mailboxes.  Cyrus IMAP, for normal mailboxes, has the user. prefix.
       create returns a 0 on success or a 1 on failure.  An error message is placed in the
       object->{'Error'} variable on failure. create takes an optional second argument that is
       the partition to create the mailbox in (I don't know if partition is rfc or not, but it is
       supported by Cyrus IMAP and Mirapoint).

       delete destroys mailboxes.  The action delete takes varies from server to server depending
       on it's implementation.  On some servers this is a hierarchical delete and on others this
       will delete only the mailbox specified and only if it has no subfolders that are marked
       \Noselect.  If you wish to insure a hierarchical delete use the h_delete command as it
       deletes starting with the subfolders and back up to the specified mailbox.  delete returns
       a 0 on success or a 1 on failure.  An error message is placed in the object->{'Error'}
       variable on failure.

       h_delete hierarchical delete (I don't believe this is RFC anything) deletes a mailbox and
       all sub-mailboxes/subfolders that belong to it.  It basically gets a subfolder list and
       does multiple delete calls.  It returns 0 on sucess or a 1 on failure with the error
       message from delete being put into the object->{'Error'} variable.  Don't forget to set
       your Separator if it's not a period.

       list lists mailboxes.  list accepts wildcard matching

       subscribe/unsubscribe does this action on given mailbox.

       rename renames a mailbox.  IMAP servers seem to be peculiar about how they implement this,
       so I wouldn't necessarily expect it to do what you think it should. The Cyrus IMAP server
       will move a renamed mailbox to the default partition unless a partition is given. You can
       optionally supply a partition name as an extra argument to this function.

       select selects a mailbox to work on. You need the 'r' acl to select a mailbox.  This
       command selects a mailbox that mailbox related commands will be performed on.  This is not
       a recursive command so sub-mailboxes/folders will not be affected unless for some bizarre
       reason the IMAP server has it implemented as recursive.  It returns an error or an array
       that contains information about the mailbox.  For example: FLAGS (\Answered \Flagged
       \Draft \Deleted \Seen $Forwarded $MDNSent NonJunk Junk $Label7) OK [PERMANENTFLAGS
       (\Deleted)] 2285 EXISTS 2285 RECENT OK [UNSEEN 1] OK [UIDVALIDITY 1019141395] OK [UIDNEXT
       293665] OK [READ-WRITE] Completed

       expunge permanently removes messages flagged with \Deleted out of the current selected
       mailbox.  It returns a list of message sequence numbers that it deleted.  You need to
       select a mailbox before you expunge. You need to read section 7.4.1 of RFC2060 to
       interpret the output.  Essentially each time a message is deleted the sequence numbers all
       get decremented so you can see the same message sequence number several times in the list
       of deleted messages.  In the following example (taken from the RFC) messages 3, 4, 7, and
       11 were deleted: * 3 EXPUNGE * 3 EXPUNGE * 5 EXPUNGE * 8 EXPUNGE . OK EXPUNGE completed

   QUOTA FUNCTIONS
       RFC2087 imap extensions.  These are supported by Cyrus IMAP and Mirapoint.

       get_quotaroot and get_quota retrieve quota information.  They return an array on success
       and undef on failure.  In the event of a failure the error is place in the
       object->{'Error'} variable.  The array has three elements for each item in the quota.
       $quota[0] <- mailbox name $quota[1] <- quota amount used in kbytes $quota[2] <- quota in
       kbytes

       set_quota sets the quota.  The number is in kilobytes so 10000 is approximately 10Meg.
       set_quota returns a 0 on success or a 1 on failure.  An error message is placed in the
       object->{'Error'} variable on failure.

       To delete a quota do a set_quota($mailbox, "none");

   ACCESS CONTROL FUNCTIONS
       RFC2086 imap extensions.  These are supported by Cyrus IMAP, Mirapoint and probably many
       others.

       get_acl retrieves acl information.  It returns an array on success and under on failure.
       In the event of a failure the error is placed in the object->{'Error'} variable. The array
       contains a pair for each person who has an acl on this mailbox $acl[0] user who has acl
       information $acl[1] acl information $acl[2] next user ...

       You could also treat the return from get_acl as a hash, in which case the user is the key
       and the acl information is the value.

       set_acl set acl information for a single mailbox.  You can specify more the one user's
       rights on the same set call.  It returns a 0 on success or a 1 on failure.  An error
       message is placed in the object->{'Error'} variable on failure.

       delete_acl removes acl information on a single mailbox for the given users.  You can
       specify more the one users rights to be removed in the same delete_acl call.  It returns a
       0 on success or a 1 on failure.  An error message is placed int the object->{'Error'}
       variable on failure.

       standard rights (rfc2086):
        l - lookup (mailbox is visible to LIST/LSUB commands)
        r - read (SELECT the mailbox, perform CHECK, FETCH, PARTIAL, SEARCH, and COPY)
        s - keep seen/unssen information across sessions (STORE SEEN flag)
        w - write (STORE flags other then SEEN and DELETED)
        i - insert (perform APPEND and COPY into mailbox)
        p - post (send mail to submission address for mailbox)
        c - create (CREATE new sub-mailboxes) (*note* allows for delete of sub mailboxes as well)
        d - delete (STORE DELETED flag, perform EXPUNGE)
        a - administer (perform SETACL)

       The access control information is from Cyrus IMAP.
         read   = "lrs"
         post   = "lrsp"
         append = "lrsip"
         write  = "lrswipcd"
         all    = "lrswipcda"

KNOWN BUGS

       Currently all the of the socket traffic is handled via prints and _read.  This means that
       some of the calls could hang if the socket connection is broken.  Eventually the will be
       properly selected and timed.
