scp username issues when ssh works

[erislover]

The company hosting my domain requires a login of the form: user@domain.com. So when I ssh, I have to type

ssh user#domain.com@domain.com

This works fine.

Now I created a key and I want to upload it. I tried using scp as in this tutorial but it doesn't seem to accept the same name format as ssh. I have tried escaping the # but it still gives me an error that the name is wrong. I've searched the web like mad for name restrictions and the man page doesn't help on this count, either.

Any ideas here? I'm pretty much a Linux newbie.

Edit: I'm sorry, this is almost certainly the wrong forum. I am not going to double-post this, as most forums do not like that. If mods move threads, can this be moved to the appropriate forum? Sorry...
