In “Blacklisted IPs/Detect Blacklisted by DNS Name,” I have blacklisted ‘*.faith’. However, it appears not to be working:

16:04:11.507 2 SMTPI-001214( [3010919] received, 7832 bytes

I also tried ‘*.*.faith’ but that doesn’t work either.  Am I missing something?  Cheers,

The above log record means that resolved to the IP from which teh connection was made, but that does not guarantee the reverse: that PTR record for the source IP resolves to that host name, which is necessary for blocking by DNS name.
