--- Comment #16 from Simon Arlott <[email protected]> --- Please remove the "v=spf1" check entirely and just return the data to libspf2 to process so that it can do it correctly. RFC7208 specifies that this is case insensitive and it is not for Exim to interpret the data. Please fix "XXX This might have to return NO_DATA sometimes" too. There are unresolved bugs in libspf2's DNS handling (https://github.com/nomis/libspf2/commit/3f4a9476aff7aabc72da03e36893fd4038a62698) so adding more bugs in Exim is not desirable. DNS lookup failures do not imply NXDOMAIN and this will incorrectly alter the outcome of the SPF check (e.g. "a", "mx" or "include" lookup failures will reduce the number of recognised hosts). Finally, the error message referring to an "IP address lookup" for TXT records doesn't make sense. -- You are receiving this mail because: You are on the CC list for the bug. -- ## List details at https://lists.exim.org/mailman/listinfo/exim-dev Exim details at http://www.exim.org/ ##
