EmailMessageLength (Function)

In french: EmailTailleMessage

Calculates the size of specified message (without loading the message). The size corresponds to the space taken by the email in the mailbox (size of message and attached files).

This function can be used with the POP3 and IMAP protocols.

Reminder Before manipulating an Email (e.g. reading it), you need to open a session using the EmailStartSession function.

Example

// Read the emails whose size does not exceed nMaxSize 
I is int
FOR I = 1 TO EmailNbMessage(UserName)
	IF EmailMessageLength(UserName, I) < nMaxSize THEN
		// Read and process the message
		ReadMessage()
	ELSE
		Info("The size of the email exceeds the maximum size and it cannot be read")
	END
END

Syntax

<Result> = EmailMessageLength(<Session> [, <Message number>])

<Result>: Integer

Total size (in bytes) of email (message and attached files).

<Session>: Character string, or emailPOP3Session or emailIMAPSession variable
