Assuming bash:

for server in $(cat server.txt)
do
  scp file.txt "$server":/tmp/
done

Parallel mode (don't use this if server.txt is massive as you can run out of bandwidth, stall the connections, and then have a hard time figuring out what succeeded and what failed):

for server in $(cat server.txt)
do
  scp file.txt "$server":/tmp/ &
done
wait

As requested, now with password support:

while read SERVER PASSWORD
do
  sshpass -p "$PASSWORD" scp file.txt "$SERVER":/tmp/
done <./server.txt

Put, in server.txt, the first server's hostname, space, the first server's password on the first line and so on.
