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. https://mxtoolbox.com/SuperTool.aspx?action=a%3atz.changeyourflight.com&run=toolpage -- Sam Clippinger On May 5, 2017, at 3:24 AM, Quinn Comendant via spamdyke-users <spamdyke-users@spamdyke.org> wrote: > I've gotten this error: > > 2017-05-05 03:16:52.533029500 spamdyke[30324]: DENIED_SENDER_NO_MX from: > bounces+1818979-7ef3-quinn=strangecode[.]c...@tz.changeyourflight.com to: > quinn[@]strangecode[.]com origin_ip: 167.89.72.110 origin_rdns: > o1678972x110.outbound-mail.sendgrid.net auth: (unknown) encryption: TLS > reason: (empty) > > Indeed, "tz.changeyourflight.com" has no MX records. > > I have tried to apply a custom setting for this sender's IP address by adding > a config file at: > > /var/qmail/spamdyke/_ip_/167/89/72/110 > > Containing: > > reject-sender=none > > Then restarting qmail smtp with `qmailctl restart`. > > I've used this method successfully in the past for `reject-empty-rdns=0` and > `reject-unresolvable-rdns=0`.
