Hi,
I am trying to block emails that match a list of domains in the sender field, see exim configuration below. My entries are in red. The uncommented entry does block emails from that sender with the "Administratively prohibited" message.
However, I want the commented entry to work which matches the deny_spoof_domains list but when I try and send an email from any sender, I get a message saying "421 Unexpected failure, please try later". Any ideas?
Thanks,
Zoe
