Question / Problem
If I want to collect bounces, only very few bounces will be recognized as being bounces. How can I alter this behaviour? Your message did not reach some or all of the intended recipients.

Answer / Solution
Most providers don’t adhere to standard formats for bounced mail, so the format of the bounced mail is the cause for not recognising a mail as bounced mail. There is very little we can do about this fact, but if you send us a bounce notification you got in original format as attachment, we will see what we can do to provide correct identification of this kind of bounces in the future.
