Yes, it did. Thanks in deed. It is not needed to edit the file for each 
user.
But there seems to be something really wired:

I added:

@domain2.tld catchall at domain1.tld

This works fine for random domains e.g. test1 at domain2.tld or 
test2 at domain2.tld.
But in case of infoi at domain2.tld (does not exist as well) there is no 
failure notice for the sender and the mail wont arrive at 
catchall at domain1.tld. This is only for the info@ account.

Any ideas?!
