Use IMAP to check Gmail on other email clients
Some clients and servers preferentially use vendor-specific, proprietary protocols , but most support SMTP for sending e-mail and POP and IMAP for retrieving e-mail, allowing interoperability with other servers and clients.

So while there may be more than one way to programmatically get emails out of Gmail with python, one option is IMAP. Next we can attempt to login. If the login fails, an exception of type imaplib. For example, to get a list of mailboxes on the server, we can call list:. With Gmail, this will return a list of labels.

So with the mailbox selected, we can now get the emails within it. To avoid having to parse the actual message data from fetch ourselves, we can use the email package from the standard library. Reliably converting to local time can be surprisingly tricky.

Python is once again comes to the rescue with numerous modules promising to assist you with all your deepest darkest date conversion needs. The code snippet above shows one possible way of converting to local time, using the capabilities of email. In contrast, the IMAP protocol specifically allows simultaneous access by multiple clients and provides mechanisms for clients to detect changes made to the mailbox by other, concurrently connected, clients.

See for example RFC section 5. Usually all Internet e-mail is transmitted in MIME format, allowing messages to have a tree structure where the leaf nodes are any of a variety of single part content types and the non-leaf nodes are any of a variety of multipart types.

The IMAP4 protocol allows clients to retrieve any of the individual MIME parts separately and also to retrieve portions of either individual parts or the entire message. These mechanisms allow clients to retrieve the text portion of a message without retrieving attached files or to stream content as it is being fetched.

Through the use of flags defined in the IMAP4 protocol, clients can keep track of message state: These flags are stored on the server, so different clients accessing the same mailbox at different times can detect state changes made by other clients. POP provides no mechanism for clients to store such state information on the server so if a single user accesses a mailbox with two different POP clients at different times , state information—such as whether a message has been accessed—cannot be synchronized between the clients.

The IMAP4 protocol supports both predefined system flags and client-defined keywords. System flags indicate state information such as whether a message has been read. Keywords, which are not supported by all IMAP servers, allow messages to be given one or more tags whose meaning is up to the client. IMAP keywords should not be confused with proprietary labels of web-based e-mail services which are sometimes translated into IMAP folders by the corresponding proprietary servers.

Multiple mailbox support also allows servers to provide access to shared and public folders. IMAP4 provides a mechanism for a client to ask the server to search for messages meeting a variety of criteria.

This mechanism avoids requiring clients to download every message in the mailbox in order to perform these searches. Reflecting the experience of earlier Internet protocols, IMAP4 defines an explicit mechanism by which it may be extended.

Many IMAP4 extensions to the base protocol have been proposed and are in common use. Much of this complexity e. The IMAP specification has been criticised for being insufficiently strict and allowing behaviours that effectively negate its usefulness. For instance, the specification states that each message stored on the server has a "unique id" to allow the clients to identify messages they have already seen between sessions. On the Add Account dialog box, you can choose the E-mail Account option which automatically sets up your Gmail account in Outlook.

To do this, enter your name, email address, and the password for your Gmail account twice. If the automatic process fails, select Manual setup or additional server types, instead of E-mail Account, and click Next. Make sure you enter your full email address for the User Name and select Remember password if you want Outlook to automatically log you in when checking email. Select the My outgoing server SMTP requires authentication and make sure the Use same settings as my incoming mail server option is selected.

While still in the Internet E-mail Settings dialog box, click the Advanced tab. Enter the following information:. You need to select the type of encrypted connection for the outgoing server before entering for the Outgoing server SMTP port number.

If you enter the port number first, the port number will revert back to port 25 when you change the type of encrypted connection. Outlook tests the accounts settings by logging into the incoming mail server and sending a test email message.
