Use the -R option to create a reverse forwarding:

ssh -n -i /root/.ssh/mailtunnel -L 1023:mailserver:25 -R 8025:localhost:25 

(BTW you don't need to be root to use ssh redirection :-)

Or use fetchmail with POP:

ssh -i  /root/.ssh/mailtunnel -L 110:mailserver:110 
fetchmail <read the manpage>

Get a new ISP?
