you can then use

mailserver.vpntunnel.ip.address:25

from the N900

All you need then is to tell the mailserver to allow relay from the vpn tunnel address range.

OK
I understand your solution
as said above I have already a tunnel simply by using

ssh -L 44999:localhost:25 root@xxx.xxx.xxx.xxx

that is default method on any Linux box as long as all ssh and server keys are already properly installed on all ends

you quote:

mailserver.vpntunnel.ip.address:25

on my linux box and local mail client it is default Linux = localhost
hence as a smtp server in the email configuration it is simply

localhost:44999 ( for my port 44999)

i have tried to use as

mailserver.vpntunnel.ip.address

anything from

localhost
127.0.0.1
192.168.2.15

??? without success
hence either there is another TO ME UNKNOWN IP in use for such ...

as a general rule
if a too such as openVPN can do
then there also should be a simple bash command line doing the very same

can u give me please the precise IP address for your LOCAL mailserver IP on your N900 ??
