--- Comment #3 from sebastian@??? <sebastian@???> ---
It is a library issue. I've a fix for the multiple records non-answer, but I
still test it.
According to the RFCs, the only appropriate action is to do not process these
records. The library should yield something like:
Received-SPF: permerror (my-hostname: error in processing during lookup of
domain of neos.io: Multiple SPF or TXT records for domain.)
The same holds for spf=none, the library does not yield any comments or headers
in that case. I like to have the Received-SPF header in all cases, if someone
does not like the header for 'none' he can simply do something like:
warn ! spf = none
add_header = :at_start:$spf_received
I'll add the spf=none case to my patch and try to get it included into the
official library sources.
