Message Retrieval

For messages, users should set up an account within Outlook using either IMAP or POP3.

IMAP is a protocol that keeps all messages and folders on the server. In addition, IMAP idle is an optional feature of the IMAP protocol that pushes all new messages to Outlook as they are received by the mail server. Unlike POP, IMAP offers two-way communication between your SmarterMail mailbox and your email client(s). This means when you log in to the SmarterMail Web interface, actions you performed on email clients and mobile devices will automatically appear in the Web interface (and vice versa).

With POP3, your mail is saved in a mailbox on the remote server until you check your mail. When you check your mail, all of the mail is downloaded to your computer and is no longer maintained on the server. If you use POP3 and are traveling or check your mail from multiple locations, you will not be able to view any of your old mail because the messages only exist on the computer on which you originally received your mail. (Note: If you have enabled Outlook to keep messages on the server, you will be able to access your messages and folders from any computer via the SmarterMail Web interface or your mobile device.)

Mozilla Thunderbird

Mozilla Thunderbird is a free, open source email client developed by the Mozilla Foundation. SmarterMail supports synchronization of email, contacts, and calendars with Thunderbird 2.

SyncML

Users of SmarterMail 5.5 or higher can synchronize contacts and calendars with Thunderbird 2 using the Funambol and the Lightning add-ons. Both add-ons are available for free from the Mozilla Thunderbird website. The Funambol add-on uses the SyncML 1.2 protocol to synchronize collaboration items and the Lightning add-on provides calendar functionality for Thunderbird.

After installing the add-ons, users will need to configure the Funambol add-on from within the Thunderbird interface.

For more information, refer to the KB article that applies to the version of SmarterMail you are using:

CalDav

Users of SmarterMail 7.x or higher can synchronize their SmarterMail calendars with Thunderbird using the CalDAV protocol and the Lightning add-on.

Message Retrieval

For messages, users should set up an account within Thunderbird using either IMAP or POP3.

IMAP is a protocol that keeps all messages and folders on the server. In addition, IMAP idle is an optional feature of the IMAP protocol that pushes all new messages to Thunderbird as they are received by the mail server. Unlike POP, IMAP offers two-way communication between your SmarterMail mailbox and your email client(s). This means when you log in to the SmarterMail Web interface, actions you performed on email clients and mobile devices will automatically appear in the Web interface (and vice versa).

With POP3, your mail is saved in a mailbox on the remote server until you check your mail. When you check your mail, all of the mail is downloaded to your computer and is no longer maintained on the server. If you use POP3 and are traveling or check your mail from multiple locations, you will not be able to view any of your old mail because the messages only exist on the computer on which you originally received your mail.

Message Retrieval

For regular and push email usage, SmarterTools offers the following methods:

  1. The BlackBerry Internet Service is a free method to push email to your Blackberry and is a service provided by your mobile phone provider (Sprint, Verizon, etc.) and can be configured to check your SmarterMail mailbox and push all new and unread messages to your mobile phone. Messages are normally pushed to the BlackBerry device with a short delay. This can configured with any version of SmarterMail as the BlackBerry Internet Service will connect to the mailbox via the IMAP protocol.
  2. An alternative free method to push messages to your mobile phone which is normally only delayed a couple minutes and simulates the expensive BlackBerry Enterprise Server (BES) which is often associated to Microsoft Exchange is to use the open source provider Funambol. By signing up with the free Funambol service, you can (just as with the BlackBerry Internet Service), configure Funambol to scan your SmarterMail mailbox for new and unread messages. If a new message is found, the Funambol service will push the message to the BlackBerry device and the Funambol client program. When you sign up for the Funambol service, they will provide you the appropriate client that should be installed on your BlackBerry device. This method provides a significant cost savings over the formal BES method with only a modest diminishment in performance.
  3. Since the BlackBerry is focused on pushing email, many consumers who are familiar with IMAP and PocketPCs miss the advantage of having access to all their messages that they see within Outlook or the webmail interface. For people who would like to log into the SmarterMail mailbox from the BlackBerry and see all of their messages as if they were in webmail, additional clients can be installed on the BlackBerry, such as the free open source application LogicMail.

Google Android

Android is an operating system designed for use in a variety of smartphones and mobile devices.
