- What does
IMAP stand for?
Internet Message Access Protocol.
IMAP is a Client/Server protocol basically designed to support
a model where users store and manipulate their received mail on
a server rather than on their own computer. The big advantage
cited for IMAP is that people who "do e-mail" from different
computers at different times have the same access to their message
store from any client computer they use, as well as from any IMAP-enabled
mail client.
- Can I use
IMAP to send mail?
No. IMAP is a protocol for receiving
mail from remote hosts.
-
Which
IMAP versions exist and which versions does Z-Mail Pro 6.1 support?
IMAP2, IMAP2bis, IMAP3, IMAP4, IMAP4rev1
are the available versions.
IMAP2 was widely used.
IMAP3 is an incompatible offshoot that has
not been widely implemented. IMAP4 is a relatively recent extension
of IMAP2, which makes servers cognizant of the MIME-structure
of a message.
IMAP2bis was the original name of IMAP4,
which has since been refined; there are some implementations
of IMAP2bis that are not IMAP4 compliant. IMAP4 also adds many
other features, including some compliant with DMSP.
IMAP4rev1 adds a few enhancements to IMAP4.
Z-Mail Pro 6.1 supports IMAP4. (Z-Mail Pro
6.2 is planned to include IMAP4rev1 support.)
-
Which
IMAP4 server types were tested?
CYRUS and University of Washington
(UW). Z-Mail Pro 6.1 supports them both.
Also tested :
latest beta PMDF from INOSOFT (For VMS -
beta stages)
Issocor’s MPLEX server for NT
NetScape IMAP Mail server
Eudora WordMail beta’s for NT
- How do
I add an IMAP4 account to Z-Mail Pro 6.1?
Using the Settings | Network Settings
command, click the Add button and select IMAP4 from the Add Transport
list. Enter the relevant account information in the new IMAP tab.
- Can
I have more than one IMAP4 transport?
Yes, as many as you like. (Z-Mail Pro currently
supports configuration of only one Internet Mail transport.
- I have created
more than one IMAP4 transport to the same IMAP4 server but I only
see one server icon?
Please note that if you use the SAME IMAP account
(IMAP server/Username pair), the additional transports are displayed
under one server icon. In order to have more than one server icon
for the same server, you need to change the name string of the
IMAP server or use an alias (for example haifa and haifa.netmanage.co.il).
- Can I decide
whether to automatically connect to the IMAP4 server when Mail
starts?
Yes. Using the Settings | Network Settings
command, select the IMAP4 tab. Click the Advanced button and select
the "Connect when mail starts" checkbox. (Selecting
this option affects only to the current IMAP transport. If you
want to apply this to several IMAP transports, you must set this
option in each transport’s Network Settings | IMAP4 tab |
Advanced dialog box.)
- Can I configure
the port an IMAP4 client uses?
Yes. Using the Settings | Network Settings
command, select the IMAP4 tab. Click the Advanced button and change
the port number in the Port number field (default port is 143).
- Can I create
an IMAP4 transport without setting up Internet mail?
Yes. Nevertheless, standard local mailboxes
(such as Inbox, Draft, and so on) are created.
- Can I connect
to an IMAP4 server off-line without changing the Settings?
Yes. Select the Offline checkbox on the Z-Mail
Pro Login dialog box (the Offline option is global, and includes
POP, if it exists).
- Can I apply Rules
to IMAP4 folders?
Yes. Rules are triggered for NEW messages in the INBOX
folder. The IMAP4 client tracks new messages by verifying the
UID of each message. (Message UID is a mechanism maintained by
the IMAP4 server to store and identify each message. The UID is
folder dependent, which means that each folder has its own range/set
of UIDs.) Each time a new UID is identified, Z-Mail Pro checks
its database to see if any Rules apply to the new message. As
the INBOX folder cannot be shared, Rules are applied to messages
in the INBOX only. Rules can only be created by the owner of the
remote INBOX.
Tip: In order to trigger new Rules on previously
stored messages in any folder except INBOX, move the messages
to the INBOX folder. In order to trigger new Rules on messages
currently stored in the INBOX, move the messages to a temporary
folder and then move them back to the INBOX.
- Why is the real
number of messages in the updated folders not displayed when Rules
are processed?
Rules processing shows the added number of messages only
unless a folder was already selected. In order to have the real
number of messages in each folder, the client must issue a SELECT
command for each added message, which is a very "expensive"
action. In order to save time and decrease the overload on the
server the client shows only the added number of messages. In
order to see the total number of messages, the user may double-click
the folder icon.
- What is the
INBOX folder?
The INBOX folder is the primary mailbox for
a user on a server. "INBOX" is a reserved name. The
mails that are received for the user (generally via SMTP) are
stored in a user configured mailbox (on UNIX, generally by Sendmail
Daemon in /var/spool/mail/<user name>). The IMAP server
lists all of the messages in this folder (file).
- How
can I avoid the display of dotted files (Only on UoW servers !)
(hidden files on a UNIX machine)?
By default, all files under the home directory are displayed.
Using the Settings | Network Settings command, select the IMAP4
tab. Click the Advanced button and insert an existing subdirectory
in the Folder’s location field.
- How do I delete
messages from the Trash folder?
Click the right mouse button anywhere on the folders tree
and select the Empty Trash command (the Settings | Preferences
| Misc tab | Empty trash on exit option does not apply to remote
Trash folders).
- Trying to remove
a folder with sub-folders underneath it resulted in an error,
"Delete failed." Why?
Removing folders is dependent upon server implementation.
UW IMAP4 servers do not allow you to remove folders that have
sub-folders underneath them (produces an error: "Directory
not empty"). CYRUS servers let you remove the folder, resulting
in a "phantom" directory. You cannot access the directory,
but its entry in the database is still kept in order to enable
the access to the sub-folders.
- When I connect
to an IMAP4 server, all shared folders seem accessible (green
hand & folder icon), but when I select a specific folder I
get the error, "Select failed." Why?
The SELECT command is only issued when you access a folder (double-click
the folder icon), which then checks the current folder attribute
in addition to other information.
Green hand & folder icon = read/write
Red hand & folder icon = read-only
Gray folder icon = inaccessible
"Stop" sign = no permissions
- Can I move
messages from remote folders to local folders and vice versa?
Yes. A few methods are available: drag and drop, the Toolbar Move
to Folder button, and the right mouse button Move to Folder command.
You may also use the right mouse button in the Folder Tree area
and select the Download command to move messages from remote to
local folders.
- My colleague
and I have the same privileges to a shared folder, but he views
the folder icon as a green hand & folder icon (read/write),
while I view it as a red hand icon (read-only)?
Some IMAP4 servers have a Server Locking feature. This is implemented
in one of two ways:
The first user to connect to a shared folder
is given read/write privileges. All users who connect afterwards
receive read-only privileges.
The last user to connect receives read/write
privileges and all users who connected earlier are limited to
read-only privileges.
- I notice from the
Log that a NOOP command is sent periodically. Why, and can I set
the period?
The NOOP command is used to reset any inactivity via the autologout
timer on the server. The NOOP command
is sent every 10 minutes (hard coded).
- Can I search my
remote directories for a string?
Yes. You may search for a string but only in the currently
selected folder.
- Does ZmailPro
use protected Authentication to login?
No. ZmailPro uses only plaintext password authentication.
- Can I have
nested folders?
Yes. Click the Right mouse button and choose the Create Sub Folder
option ,then in the Create Folder dialog insert the name of the
new folder with a delimiter at the end. (The delimiter is server
dependent)
