In french: <Variable emailSessionPOP3>.OuvreSession

Starts a session for managing emails via the POP3 protocol.

Note To open an e-mail reading session (via POP3 protocol only), use the EmailStartPOP3Session function.

...
// Ouvre une session pour l'envoi d'un email par le protocole POP3 
IF MaSessionPop3.StartSession() = True THEN
	NomUser = MaSessionPop3.Name
ELSE
	NomUser = ""

Syntax

Start a POP3 email session Hide the details

<Result> = <POP3 session>.OpenSession()

<Result>: Boolean

True if the session was started,
False otherwise. If an error occurs, the ErrorOccurred variable is set to True.
To get more details on the error, use ErrorInfo with the errMessage constant.

<POP3 session>: emailPOP3Session variable

Name of the emailPOP3Session variable corresponding to the email session to handle.

Remarks

POP3 and SMTP protocols

The different parameters passed to <emailPOP3Session variable>.StartSession are supplied by the Internet Service Provider or by the network administrator.

An Internet connection is required to manage the emails. Several cases may occur:

The user uses a direct connection to Internet (cable or ADSL): no specific operation required.
The user uses a modem to connect to the Internet: the NetOpenRemoteAccess function opens the Internet connection.

By default, if only the IP address of POP3 server is specified, this address will be used by the email server that uses SMTP. The IP address of SMTP protocol must be specified only if the POP3 account and the SMTP account do not use the same computer.

Authenticated SMTP

The SMTP authentication cannot be performed by <emailPOP3Session variable>.StartSession. To start a POP3 session and an authenticated SMTP session at the same time, you must use both EmailStartPOP3Session and EmailStartSMTPSession.

Timeout

The timeout can be set using EmailSetTimeOut.

Gmail: What should I do if a connection to Gmail (SMTP, IMAP, POP3) fails due to a certificate error?

Since the end of August 2017, Google has deployed a new certificate: Google Internet Authority G3. Unfortunately, the Windows API for checking certificates does not validate this certificate.

Therefore, starting a POP3, IMAP or SMTP session may fail with the error "The certificate string was not issued by a trusted authority".

To validate the certificate, all you have to do is modify the management mode of emails. The WLanguage EmailConfigure function allows you to change this mode and to no longer use the Windows API that locks this certificate. The following code must be added before starting the session via <emailPOP3Session variable>.StartSession:

// Activation de l'implémentation multiplateforme
EmailConfigure(emailParameterMode, 1)

Remarks:

As of version 23 Update 1, you no longer need to call the EmailConfigure function: WLanguage automatically uses the email management mode appropriate to the session.
You can handle certificate errors on an SMTP session using the IgnoreError property of a variable of type emailSMTPSession.
