It really shouldn't matter which server you upload to unless you're
posting to newsgroups that aren't on your other server. If you need
to separate your replies for uploading to different servers I believe
you'll have to use separate yarn sessions to create outgoing SOUP
packets containing messages for uploading to one particular server.
E.g., I do email and the local cybergate.* newsgroups using UQWK on
my shell account and all other newsgroups with supernews. I make sure
my outgoing SOUP packets have either gate.net stuff or supernews
stuff, but not both.
