Usage of 'intrude'

[Daemon99]

Can some one please tell me which of the following two sentences is correct?

1) Sorry for intruding into your mailbox
2) Sorry for intruding your mailbox

Does such a usage exist?

Neither is appropriate. 'Intrude' = enter forcefully, illegally, etc. A mailbox is too small to enter.

Thanks Mister Micawber.

Can't we use it figuratively either? By the way, I meant emailbox when I wrote mailbox.

It is not wise for non-native speakers to use words figuratively unless they have found precedent for it; it usually leads, as here, to confusion.
