I'm not really understanding the internet.
Can I do my own SMTP server and send mail off to the right place
without having the device open to random internet connections?
You can first place your SMTP server behind a firewall to block the
undesirable ports.
Second, your SMTP may allow to specify the port you desire to use. This
the case with exim4.
With exim4 you can use certificate as well.
I'm uncertain who validates the certificate.
Is just for sending. Presumably any abuse would get blocked by one of
the hops?
