We are using the BM 3.91 FTP proxy which of course uses the FTP proxy user@host (if @ is set as the separator which we set ours to) when using FTP client software.

We've just had a company give us a piece of software that requires FTP access but uses @ symbol in the username of user that accesses the FTP site. I'd rather not change from using @ as the separator - lots of FTP software plays nicely with this and I don't want to give direct access as we operate a DMZ that limits traffic between internal and external hosts except via the proxy (which acts as an endpoint in both directions).

I guess the question is: Is there any way to escape the @ symbol in the username with bordermanager? e.g.

so that BM ignores the initial @ symbol?
