I don't know if this error was also in 2.2. In such case IMO we should consider it a blocker :-( , because after an upgrade from 2.2.0 to 2.3.0 the systems having <checkValidSenderDomain> set to true would lose messages.

The fix was ok for 3.0 in trunk, but not for 2.3.0.

[Vincenzo Gianferrari Pini]

The fix now is checking senderAddress != null, instead of sender != null.

Closing issue fixed in released version.
