I send mails from my precondition with the service method

    sendMail(MailSender sender, String toAddress, String subject, String msg, String cc)

For only one recipients it works fine, but I fail to use this method to send mails to multiple recipients. I tried it with comma separated mail addresses (with and without spaces e,g,, and with semicolon separated mail addresses. But every time I receive the following exception

javax.mail.internet.AddressException: Illegal address in string ``,''

So, how must the toAdress parameter be formatted so that the mail will be send to multiple recipients?

Thanks and regards

As a workaround:
you can chop down the string that contains multiple email addresses so that each piece contains only one email address. Then you can invoke the sendMail service method once for each email address.

I think that will work too. If I find no other solution I will try to send a mail for each recipient. But I prefer to send one mail to multiple recipients.
