Chapter 4 - Webmail

If you wish, you can configure your SME Server so that users can access their email via a web interface. Once webmail is enabled, users will be able to access their email from the local network or anywhere in the world via the Internet using any web browser which supports Javascript and tables, which almost all browsers do.

For added security, SME Server supports the use of https Secure Socket Layer (SSL) connections. When users connect using SSL, all communication between their browser and the server is securely encrypted to prevent eavesdropping.

Template:DrawBoxNote

If you intend to enable webmail, you should consider whether your users will use webmail exclusively or will use webmail part of the time (for example, when travelling) and a regular email client the rest of the time. If they plan to use webmail and another client, it may be easier if the other client uses the IMAP protocol. If the client uses POP3, email messages will be pulled down from the server into the local email client and most email clients default to deleting the message from the server at that time. Messages will therefore not be visible when the user later logs into webmail. If IMAP is enabled on the local client, messages remain on the server at all times and will be visible both from the local client and via webmail. For more information on IMAP and POP3, see the section in chapter 2.

A second issue is that using webmail will consume resources and bandwidth from your server. We recommend that you evaluate the suitability of your server hardware if you plan to use webmail, but webmail can always be disabled later if you find that your system is not performing well.

Enabling Webmail On Your System

Because the use of webmail can be resource-intensive, the server ships with webmail disabled by default. To enable the use of webmail, the server Admin must perform the following steps:

1. Connect to the server-manager and login as the admin user.

2. In the Configuration group, click on email and then the 'change email access settings' button. You are given two webmail options:

  • Disabled
  • Enabled (Allow HTTPS secure) - Allows users to connect only through a secure SSL connection.

After you enable webmail, your users should be able to connect and use webmail.

Starting Webmail

To use webmail, a user first needs a valid user account and password on the server. Next, the user opens up a web browser and points it to the server using an address resembling the following URL: https://www.tofu-dog.com/webmail/

Template:DrawBoxNote

Note that if the server is behind another firewall, that firewall will need to allow traffic through on TCP port 443 in order for SSL connections to take place.

Logging In

Once connected, a user will be given a login screen similar to that shown in the screen below. From this screen you can read the help menu (by clicking on the link for New User Introduction at the top of the page) or login with your normal network user name and password. Note that IMP supports a wide variety of languages in addition to English.

 

Viewing The Inbox

Once logged in, you will see your Inbox, as shown in screen below.

 

Let's take a quick tour of the Inbox window.

In the top left corner is a pop-up menu that shows the list of your available mail folders. In your first webmail session, the only folder choice will be INBOX . As soon as you send an email message, a folder called sent-mail will be created and available in the menu. You can also create additional mail folders at any time.

In the top center portion of the window is a status message indicating the folder you are in and the number of new or recent messages in that folder.

On the left side is a navigation menu allowing you to compose new messages, modify contacts, create folders, modify preferences or logout of the webmail system.

In the main part of the window are the actual messages. Each message has an icon denoting its status at the far left, the date/time of the message, who it is from, the subject and the size. Messages may be sorted by clicking on the column heading. You can read a message simply by clicking on the subject or sender of a specific message. The envelope/arrow icon that you can see in the status area of the second message in the image above indicates that this message is new.

We will describe the various functions in greater detail later in this chapter, but this should be enough to get you started.

Logging Out of Webmail

Before we discuss the features of webmail, it is important to emphasize that you must always click on the Logout menu item when you are finished using webmail. If you do not do so, anyone else who uses your web browser on your computer (until you exit your web browser or logout of/shutdown your computer) will be able to read your messages and send messages from your account. After a successful logout, you will see the webmail login screen with a message at the top of the screen indicating that your logout was successful.

Composing Messages

To compose a new message, click on Compose in the menu on the left. You should see a screen similar to that below.

 


At the top of the compose screen, your available options include the ability to spell-check the message in your language of choice, or to cancel, save a draft or send the message.

If you choose to save a draft, your message will be saved in a folder called drafts . You may later retrieve this message by using the popup menu in the upper left corner to switch to the "drafts" folder.

Below that are the familiar email fields for you to fill out. At the bottom of the page, the menu of commands is repeated for your convenience.

Reading Messages

To read a message, click on the From or Subject fields of the message. You should see a screen similar to the one below.

 

You now have several options. You can:

  • Delete the message.
  • Reply only to the sender.
  • Reply to all of the original recipients.
  • Forward the message to someone else.
  • Bounce the message to another person (similar to "Forward" but without providing you the opportunity to comment). *5
  • Save As - save the message to a text file.

By clicking on the Reply button, you will be able to enter a reply window such as that shown below. Notice that the original message text is "quoted" with a ">" character in front of it. At this point, you can type more text or edit existing text, add or delete recipients, spell-check the message and do anything else that you could do in a normal compose window. Again, you can choose to cancel the message, save a draft or send the message.

 


#5 In fact, the bounce command will send the message on to a third-party without indicating that you were the one forwarding it. So if "ffrog" sent a message to the "sales" group (of which you are a member) and you then bounced it to another user, that user would see the message coming from "ffrog" and going to "sales", but your name would not appear anywhere in the visible headers. Compare that to a "forward" command where the recipient knows you are the person forwarding the message.

Deleting Messages

You can delete a message while reading it, as mentioned previously, or you can delete a message - or a group of messages - from the Inbox view.

 


To do so, check the box next to each message you wish to delete. After that, press the Delete text button directly above or below the list of messages on the left side. You will now see a trash icon next to the checkbox and a line through the messages.

As an example, in the image above, our user (ffrog) wants to delete the second and third messages. He can click on the checkbox next to each message and then click Delete . This will produce a screen such as that below.

 

If you do not want to see the deleted messages, you have two choices. If you click on the Hide Deleted text button on the right side, the messages will be hidden from view, but will still be there and could be recovered with the Undelete button. If you choose Expunge, the messages will be permanently deleted.

Using Contacts

The server webmail system provides two means of keeping track of e-mail addresses. First, you can have your own Contacts list. Second, you can easily access the company directory that lists all users and groups that have been created.

You can view and edit your contacts through two menu choices. From the left menu you can choose Contacts . This allows you to view or edit contacts, but does not allow you to add a contact to an e-mail list. To add a contact, you must open the Contacts window from the "Contacts" link in a Compose window, as highlighted in the image below.

 


In either case, you will find yourself viewing a window that looks like the one below.

 


If this is the first time you have entered the Contacts window, you will not see anything next to the "Select" button. Normally, though, you will see a pop-up menu with all of your contacts in it (as seen in the window above where "bob <bbass@e-smith.com>" appears). To enter a new contact, simply type the e-mail address, a "nickname" that will appear in the Contacts list, and the full name of the person. You must fill out all three fields. Then click Add Contact .

To update a contact's information, select the user's name/address from the contacts pop-up menu. The information should automatically appear in the fields. (If it does not, after selecting the entry from the pop-up menu, press the Select button next to the menu.) Enter the new information and click Update Contact . In a similar fashion you can delete a contact by selecting the contact from the pop-up menu and pressing the Delete Contact button.

As mentioned earlier, if you entered the Contacts window from the link in the Compose window, the three buttons - Insert into To:, Insert into Cc:, and Insert into Bcc: - will allow you to transfer the contact information directly into the Compose window.

To search the company directory, use the lower section of the Contacts window labeled LDAP Search *6. You have the ability to search either the entire name field or just the surname. Enter the text you are searching for in the entry box and choose how you want to compare the text against the directory. The default is to search for entries where the name is the text you enter, which requires an exact match. You may find it more useful to search for entries where the name contains the search text. A search with "contains" will find names where the search text appears somewhere in the name.

After entering your text and choosing your search options, press the Start Search button to query the directory. As shown in the screen below, your results will be returned in a new LDAP Results section of the same Contacts window. As with the section at the top of the screen, you choose your entry from the pop-up menu (or press the Select button if your entry is displayed already) and the information should appear in the entry box below. Assuming you entered Contacts from the link in the Compose window, you can now insert this information into the To, Cc or Bcc lines of the Compose window.

Note that you also have the option of inserting this entry directly into your Contacts list. If you have a large company directory, you may find this a useful way of ensuring that frequently used contacts are readily available.

Template:DrawBoxNote

 


#6 The search is called an LDAP search because the directory is queried using the Lightweight Directory Access Protocol (LDAP), one of the most common protocols used on the Internet for searching directories.

Changing Webmail Preferences

By clicking on the Preferences link on the navigation menu, you can modify preferences for your webmail session, as shown in the screen below.

 

You have four preferences you can configure:

  • Signature - You may include any text that you wish to appear by default at the bottom of your email messages. Once configured, it will always appear at the bottom of a Compose or Reply window when you enter that window. You can, however, delete it for a specific message simply by editing the text in the Compose or Reply text window.
  • Full Name - If you leave this blank, all of your messages will appear to recipients as having come from your email address. If you enter text here, recipients will usually see that text first instead of your e-mail address.
  • From Address - By default your From address is your regular system email. You do not need to set it here . Enter an address here only if you want people to see a different reply address than your normal system-generated e-mail address.
  • Preferred Language - This allows you to specify the language used in the menus.

When you are done modifying your preferences, press the Save Preferences button at the bottom of the page.
