+**(33) Why are edited sender addresses not working?**
+
+Most providers accept validated addresses only when sending messages to prevent spam.
+
+For example Google modifies the message headers like this:
+
+```
+From: Somebody <somebody@example.org>
+X-Google-Original-From: Somebody <somebody+extra@example.org>
+```
+
+This means that the edited sender address was automatically being replaced by a validated address before sending the message.
+
+Note that this is independent of receiving messages.
