llEmail, llGiveInventory - grid wide - problem

hi,
I tried to script a so called virtual server, that receives an email from a certain object some place in SL and then sends inventory items to this object.
So far I managed to make it work without problems at my place, but if I tp to a different sim, it doesnt work any longer.

The sender email contains a password and the key of the prim that contains the script. The server checks the password and sends the item to the key it got the email from. Isn't that the way to do it?

Why does it only work on the sim, where the server is?

Any help appreciated.

Thanks

llGiveInventory will transfer items to *agents* anywhere on the grid (even if offline), but will only give items to *objects* in the same sim. This is because there is a central repository of all agents' UUIDs, whereas object instance UUIDs are probably only tracked at the sim level, and therefore the system doesn't want to search each and every sim on the grid for the object you're attempting to give inventory to.

thank you very much

by the way...is there a different way to do that?

Thanks.
