To get an account on a particular organization's IMP system, you will need to contact the support staff at the organization. IMP's developers have no connections with the organizations that use IMP.
If you wish to try IMP without doing so through a particular organization's system, there is a demo site available which will allow you to access your existing mail account over IMAP or POP3. The demo site is unsupported and comes with no guarantee or promise of continued availability.
If you are unable to login to IMP, contact your organization's support staff. They are the only ones who can manage accounts within your organization; IMP's developers cannot.
To risk sounding repetitive, contact your organization's support staff for all information regarding your local mail system. You can also send mail to a friend requesting that they reply, and observe the address to which their reply was sent.
[IMP 2.2] If your organization's installation of IMP supports password changes over the Web, you will see a Change Password link in IMP's menu. Click on that link in order to change your mail password. If that link does not appear in the menu, your support staff will be able to inform you of password-change procedure at your site.
[IMP 3.x] If your organization's installation of Horde and/or IMP supports password changes over the Web, you will see a Password link in Horde's and/or IMP's menu bar. Click on that link in order to change your mail password. If that link does not appear in the menu, your support staff will be able to inform you of password-change procedure at your site.
[IMP 2.2] In IMP's status bar, above the mailbox index or message body part of the display, "new" refers to messages which have not been read since they arrived, while "recent" refers to messages that have arrived since the last time you looked at the mailbox's index.
A plus sign ("+") [IMP 2.2] or image of a face [IMP 3.x] in the left-hand column of an entry in the mailbox index view means that that message was sent directly to you, and not only Cc'd to you or sent via a mailing list. In other words, your address appears in the To: header.
IMP's mailbox view shows the recipient in the From column on messages for which you are the sender. (In other words, since you sent it, you know who the sender is, so IMP tells you who you sent it to.) This is particularly useful for the sent-mail and drafts folders.
Depending on the way your site has configured IMP, you may be presented, when you click on the Folders link in IMP's menu, with a list of mailboxes to which you can subscribe (and unsubscribe). Since it is possible to have a very large number of mail folders in your account but not actively use all of the folders -- the others, for instance, being archives of old mail -- IMP allows you to specify which folders you wish to be able to access in IMP. Subscribing to a folder makes it appear in the lists of folders to which you can copy, move, and save messages and for which you can display a message index.
If your site's IMP configuration allows you to use multiple folders but does not require you to subscribe to the ones you wish to access, you will always see all of your folders in IMP's folder lists.
[IMP 2.2] When you tell IMP to delete one one or more messages (by clicking Delete in the message view, or by selecting the check box to the left of the message in the mailbox index view and then clicking Delete), the mail is only marked as deleted, and is not immediately removed from your mailbox, giving you the opportunity to decide to undelete it. If you are certain you will not need the deleted message(s), click on Purge Deleted (or, in older versions, Expunge) in the mailbox index view. If you only wish to make IMP stop displaying the deleted messages, without permanently removing them, click Hide Deleted from the mailbox index view.
[IMP 3.x] IMP 3.x can work in two modes: marking mail as deleted, and moving deleted messages to a Trash folder. In the first mode, it works the same as IMP 2.2 as described in the above paragraph.
If you are using the Trash folder feature, it acts somewhat differently. When you tell IMP to delete one or more messages (by clicking Delete in the message view, or by selecting the check box to the left of the message in the mailbox index view and then clicking Delete), the mail is moved to a Trash folder, giving you the opportunity to decide to undelete it (remove it from the trash) later. If you are certain you will not need the deleted message(s), click on Empty Trash folder in the mailbox index view. In addition, you can have IMP schedule to automatically empty your trash folder at various intervals via the "Maintainence Operations" section of Options.
To send mail to more than one person, separate their email addresses in the To:, Cc:, or Bcc: header (or a combination of all three) with commas (","). Do not use semicolons (";") to separate lists of email addresses.
[IMP 2.2] Instead of opening the Contacts List dialog, you can save time when sending mail to people in your Contacts List by typing their nickname in the appropriate header field in the Compose window itself.
[IMP 3.0] Instead of opening the Address book window, you can save time when sending mail to people in your Address book by typing their name, or part of their name, in the appropriate header field in the Compose window itself and the using the Compose window's Expand Names button to expand the name to the full address. If multiple Address book entries match, you will be given a selection list of all the matching entries from which you may select the desired address.
[IMP 3.1] In addition the the Expand Names button discussed above in IMP 3.0, IMP 3.1 has an Address Book button which can be used to look up names in the Turba Address Books (if available).
[IMP 2.2] Each Contacts List entry can only contain a single email address.
[IMP 3.x] Full support for multiple addresses is still being implemented. But, in most cases you can store multiple addresses in a single Address book entry simply by listing all the email addresses in the Address book Email field separated by commas. Do not use semicolons (";") to separate lists of email addresses.
Note that the number of addresses that fit in a single entry may be limited.
Due to the nature of Web-based mail, attaching a file to a message you are about to send is slightly different than what you may be accustomed to in conventional mail programs. Attaching a file requires two steps. While composing the message:
Please note that for large files and/or slower Internet connections, the process of uploading and attaching your file to the email may take a while. Please be patient and do not click on other things while you are waiting.
To see the entire message header, click the Message Source link in the Parts section of the message view. This will show you the raw mail message in the mailbox, including full headers and any attachments in encoded form.
