ssh -L 44999:localhost:25 root@xxx.xxx.xxx.xxx
and the mail client thus has an smtp server
localhost:44999

is there a way to use port forwarding for eMail on a N900 and is there a localhost MTA on a N900 to accept and forward such mails ??

of course there might be third party mail accounts
BUT I have a strict SPF record set for my mail servers to ONLY have my own clean IP addresses as used sender IPs. I love to keep my SPF record that strict.

Any help apreciated
