So which ones are strange? First and fourth row are just info.

Warning means you have that setting defined twice. You should check what Postfix does if it is defined twice: ignore the first one, or second one? Probably you can comment one of those out so that you get rid of the warning.

When alias changes, it reloads, that is OK.

The large number of messages going from the non-existent account [email protected] to .pl and .ru MX servers is the strange part. Other lines are immediate context of a representative example. Thanks for the context for the warnings.
