This Session object is then used to construct a new Message object:
Message msg = new MimeMessage ( session );
Here I specify the MimeMessage class in particular since I know I'm sending Internet
email. However, this is the one place where I do explicitly choose a format for the email
message.
Now that I have a Message object, I need to set up its fields and contents. The From:
address and To: address will each be javax.mail.internet.InternetAddress objects.
You can provide either an email address alone or an email address and a personal name:
Address bill = new InternetAddress ( "god@microsoft.com" , "Bill Gates" );
Address elliotte = new InternetAddress ( "elharo@ibiblio.org" );
The setFrom() method specifies who's sending the message by setting the From: header.
There's no protection against forgery. It's quite easy for me to masquerade as Bill Gates
at a (presumably) fictitious email address:
msg . setFrom ( bill );
The setRecipient() method is slightly more complex. You not only have to specify the
address that the message will be sent to, but how that address is used; that is, as a To:
field, a Cc: field, or a Bcc: field. These are indicated by three mnemonic constants of the
Message.RecipientType class:
Message . RecipientType . TO
Message . RecipientType . CC
Message . RecipientType . BCC
For example:
msg . setRecipient ( Message . RecipientType . TO , elliotte );
The subject is set as a simple string of text. For example:
msg . setSubject ( "You must comply." );
The body is also set as a single string of text. For example:
