使用javax.mail发送给多个收件人

Question

I've got the following...

msg.setRecipient(Message.RecipientType.TO, new InternetAddress(to));

Which works fine but when I attempt to add this multiple times (with different variables for to ) it only sends to the last statement. I've also attempted sending something like email1@gmail.com :email2@gmail.com as the to variable but this throws back an error.

Does anyone have any suggestions as to how I'd send mail to multiple recipients using JUST one e-mail and not multiple e-mails using javax.mail ?

Answer 1

msg.setRecipients()将地址数组作为第二个参数。

Answer 2

Use Message's subclass - MimeMessage. It implments the setRecipients(Message.RecipientType type, Address[] addresses) method.

Furthermore, you could choose which specific message you need to use: IMAPMessage, POP3Message, SMTPMessage .
