[trustees] Trustess breaks postfix maildir delivery

[Rob S. <ro...@rs...>]

All,

 	I just discovered that postfix has a problem with delivering to a 
maildir mailbox when trustees is enabled. The problem manifests itself as 
the delivery agent complaining about Invalid cross-device link .I believe 
it creates the file in another dir and then hardlinks it to 
its final destination and deletes the original. The quick fix was to 
return 0 in the trustees_inode_link function, but for obvious reasons that 
isn't optimal. Do you have any suggestions on how this could be handled ?

Thanks,
-Rob
