Hi,
Here is my problem. I have a Raspberry running in my home network, and I
want it to be able to send me email. I set up a send only postfix on it
and that works fine. The email that arrives on my email server fails a
couple of tests - domain not found and need FQDN.
The email is from root@raspberrypi.
Obviously I could change that, but I don't think I could get it to a
proper domain and FQDN, and I'd rather not if I can avoid it. The IP
address it arrives from is random as it's sometimes through a VPN.
I have full control of the email server, which is a latest standard
Debian/postfix/dovecot set up.
So what I'm looking for is the easiest way of accepting that email,
while staying pretty secure. I could update the sending domain to be
some random unguessable string.
There appear to be some ways that might work (TLS fingerprint of the
client sort of stuff?)
A simple equivalent of mynetworks, but for a from address rather than an
IP/network would be ideal.
Thanks in advance for any suggestions.
regards
Dave
