Spf smtp status softfail MTA option

SPF MTA options: (2, 4, or 5)
The  MTA option controls whether  SPF SoftFail results are ignored (considered as successes), interpreted as temporary failures, or  interpreted as permanent failures, with values of 2 (the default), 4, or 5, respectively, controlling this. (To emphasize, this option is controlling the interpretation of SPF lookups that succeeded in finding a relevant SPF record in the DNS and where the SPF record specified an explicit SoftFail for the exact domain name being checked. For the case of a SoftFail "all" SPF record that matched the domain name in a more wildcarded way, see instead the   MTA option. Or for the interpretation of DNS-level temporary errors in the SPF lookup attempt, see instead the     MTA option.)
