Thanks Sam.

BTW, I created a script to automate creating the custom sender configuration 
files using the _ip_ and _sender_ directory structures:
https://gist.github.com/quinncomendant/4e62a0e4ab82d7b6fe0dc3947510c4c7

Use it like:

sudo spamdyke-sender-conf 111.222.333.444
…or:
sudo spamdyke-sender-conf tz.changeyourflight.com

It may need customization for different systems. I'm using qmailtoaster.org's 
implementation.

Ah, I should have asked.  Yes, that option should work.

Update: I added `reject-sender=none` to /etc/spamdyke.conf and these errors 
started appearing in the log:

2017-05-05 06:33:46.873563500 ERROR: Unknown configuration file option in 
file /etc/spamdyke.conf on line 33: reject-sender

I realize now this config option is only for spamdyke 5. I'm currently using 
spamdyke 4.3.1+TLS+CONFIGTEST+DEBUG+EXCESSIVE.

So I presume the corresponding config option for version 4 is 
`reject-missing-sender-mx`. Would the correct syntax for disabling this in a 
spamdyke/_ip_/… directory be like this:

reject-missing-sender-mx=0

?

That should do it, assuming you also have a line in your main configuration 
file that says:
config-dir=/var/qmail/spamdyke
However, from the rDNS name, it looks like that sender could come from a huge 
list of IPs.  You might consider turning off the filter for the domain instead, 
like this:
/var/qmail/spamdyke/_sender_/com/changeyourflight/tz

And it's always possible you found a bug.  If you still can't make it work with 
the _sender_ folder, let me know and I'll do some testing too.

For what it's worth -- tz.changeyourflight.com doesn't just have no MX records, 
it has no DNS records at all.  I don't see any way that return address could 
work.
