Hello,

We've seen some occurrences of an error handling your API response from your repo.

We're calling PostmarkClient->getOutboundMessageDetails and we are seeing errors popping up with the message Warning: Undefined array key "MessageEvents" .

I see in the constructor of PostmarkOubdoundMessageDetail that you have a check on whether the array key MessageEvents is empty or not.

If the check is true, you instantiate a PostmarkMessageEvents with no arguments, which results in an empty array being passed as a default value but in the constructor of this class, you do not check whether the key MessageEvents is there before iterating on it.
