Re: starting ssh port forwarding from inetd
i see 1 rproblem there there is no POP3 server on the pop3 line so there
is no way to read mail without the actual pop client. if your that
paranoid go with something like IPSEC, or use a POP server that supports
APOP(obsolete?) or SSL. as for SMTP ..well use IPSEC. i hope your not
planning on encrypting your SMTP port and expect incoming mail to work
right. if its all internal thats fine though ..although i've
(personally) never herad of anyone trying or even wanting to do what your
doing.
