Sending email, via javamail smtp, results in messagePartiallyDelivered on a completely successful send

Question

Sending email, via javamail smtp, with 2 addresses listed in MIME headers but only 1 address used in send function seems to result in a messagePartiallyDelivered, regardless of the fact that the 'one' address provided to the send function successfully received the message.

Is this the expected behaviour ?

The javadocs for javamail are not very well filled out, so it is hard to tell if this is the behaviour I can expect with any implementation of javamail (be it sun/oracle, or gnu).

Answer 1

Do you have mail.smtp.reportsuccess set? If so, that's the expected behavior.

Otherwise, it would be helpful to see the protocol trace and debugging out .
