* Using WP 1.5.2 to compose.

* Posting a dummy item with trackbacks sent to two separate domains running WP

* First test:

   trackback field contains [URL1] [URL2]
   both trackbacks received at both ends

* Second test:

   trackback field contains [URL1], [URL2]
   only second trackback is received

Hope it helps,
