Error while sending email to Multiple Recipients

Question

Hi,
I am trying to send email to multiple recipients .It works fine if all the email-addresses are valid. If even one is invalid throws exception .I wish to send it all the valid addresses even if some are invalid as this email will be going to 3000 users some of them will be wrong addresses.
Help is greatly appreciated.

Exception thrown:
Exception in SendEmail.setAddress as :javax.mail.SendFailedException: Invalid Addresses;
nested exception is:
javax.mail.SendFailedException: 550 <[email protected]>... User unknown
Here is the main piece of code:
message.saveChanges();
Transport transport = session.getTransport("smtp");
transport.connect("myhost", "", "");
transport.sendMessage(message, message.getAllRecipients());
transport.close();

Answer 1

Hi there,
Well I find the easiest way is to use a comma delimited string with the following bit of code.
msg.setRecipients(
addrType,
InternetAddress.parse(smtpAddress, false));
addrType will be TO,CC or BCC
smtpAddress is a comma delimited string that I get from the results of a SQL Select request (looks something like "[email protected],[email protected],....,....,...."
The boolean false is to prevent the parse checking the validity of the SMTP addresses as I prefer to deal with this by letting the SMTP server tell me which addresses are no good.
Hope this helps,
