Sending and seeing multiple recipients
I've been searching the forum and looking at old posts about using JavaMail to send to multiple recipients. I can send to multiple recipients ok, but my problem is I want to see all the recipients on the To line of the email. I tried a few different ways of setting the recipients but they all give me the same thing.
Right now I'm setting the recipients like this:
String recipient_list ="addr1@domain.com,addr2.domain2.com"
msg.setRecipients(Message.RecipientType.TO,InternetAddress.parse(recipient_list,false));
Transport.send(msg);
The problem I have is that the messages get delivered to each recipient, but they are the only ones in the To field. The other address(es) do not show up.
In the debug of the smtp connection it only shows me the last address in the list:
DEBUG SMTP SENT: RCPT TO:<addr2.domain2.com>
DEBUG SMTP RCVD: 250 2.1.5 <addr2.domain2.com>... Recipient ok
Verified Addresses
addr2.domain2.com
How do you get all the recipients to show up in the To field on the resulting email?
Any help is appreciated. Thanks,
James

What you're doing should work. That's the technique the msgsend.java
demo program uses, and it works fine for me.
Maybe I don't understand what aspect of it you don't think is working?
Certainly the debug output should include a RCPT line for each of
the recipients you list. And since you say that the message is
getting delivered to every recipient, that must be working. It's also
true that every recipient should be included in the To: header in
the message.
Maybe you can try the msgsend.java demo program and post the
output if you don't think it's working? For example, here's what I get:
$ java msgsend -d "addr1@domain.com, addr2@domain.com"
To: addr1@domain.com, addr2@domain.com

duh! no, I didn't. :-(
ok, I entered in some data, hit enter, hit . so there was just one on a line by itself, then hit ^D. At that point I get the error below. The good news is that it did in fact verfiy both addresses, which I was not getting with the older javamail.
I'll have to do some searching on the error below.
thanks,
James
