This is what I have done on the screen server to achieve dynamic

Why would you tie this to your ssh command at all?
I have a postcmd in my shell like this (this is tcsh):
alias postcmd 'printf "\033%s%s %s %s\033\\" "k" "\!#:0" "\!#:$"
"[$HOST]"'
You need to create that alias on every hosts. I have 300 of them.
Nope, just the one I ssh out from. I ssh into about as many hosts as you
do, but only one or two "home" servers (where my keys live, etc).
Better put, your shell only needs to be modified on machines you run
"screen" on.
with your setup when you ssh to a host it changes the title fine, but
when exit from it
the title does not change back.
Yes, when I exit from it, it changes back because my prompt on my main
machine is set thusly:
set prompt="%{\ektsch [$HOST]\e\\%}"\%
Ok it is more than just postcmd. Let me know if you can make it work
for bash users.
I dont use tcsh
This is basically what you're looking for:

I posted a small example of how to use it with screen (and other long
running commands) for window title changing in an earlier thread:
http://lists.gnu.org/archive/html/screen-users/2009-04/msg00043.html
There are ways around the LC_* "requirements" I posted earlier.

I have followed the advice Brian gave here, and I can set this
up easily on my own system. Yet, when I start a terminal session, ssh
to another host from where I start screen, this solution with preexec
doesn't work.
I have copied my (working) .bashrc, .screenrc and preeexec.bash over to
the remote system, so the files are identical, but as to why this wont
work is eluding me. How can the fact that i come from a remote host,
with the same setting, be in the way of sending the dynamic title? Can
any one shed some light on this?

I have the following in my bashrc:
. ./preeexec.bash
set_xterm_title () {
local title="$1"
case "$TERM" in
xterm*|rxvt*)
echo -ne "\e]0;$title\007"
;;
screen)
echo -ne "\033k$title\033\\"
;;
esac
}
precmd () {
set_xterm_title "address@hidden `dirs -0` $PROMPTCHAR"
}
preexec () {
set_xterm_title "address@hidden"
}
preexec_install
And in my screenrc:
setenv SCREEN_RUN_HOST $SCREEN_HOST
setenv SCREEN_RUN_USER $USER
setenv LC_SCREEN_RUN_HOST $SCREEN_HOST
setenv LC_SCREEN_RUN_USER $USER
