There are a couple of ways to address this issue. However, I'm a bit
confused regarding your description. 

When you upload a file to another account on a different computer, the
file should be owned by the remote account owner (i.e. your identity
on the remote system). As the file is owned by the remote account, it
should be possible as the remote user identity to modify its mode. In fact, I
would have thought the file would have recieved whatever the umask
setting is of the remote user account. 

What method are you using to transfer the file to the remote system?
What does a long directory listing show as the owner, group and
permissions of the file on the remote system once it has been
transferred?

The simple solution is to change your umask on your originating system
in your .profile (or whatever the init file for your shell is).
However, I think this is not a good solution as it will reduce your
privacy/security on the source system - to what extent that is an
issue only you can judge. However, I suspect there is a better
solution then this quick 'fix'.
