如果我将SPF策略v=spf1 include:_spf.google.com -all到我的网域,那么-all产生一些影响,或者_spf.google.com都会“inheritance”到我的网域吗?
简而言之, include通常只会导致匹配(如果通过),否则不匹配否定结果(或者可能是错误条件中的错误)。 包含logging之外的具体行为,超越通过/不通过,是无关紧要的。
从SPF规范的include部分 :
+---------------------------------+---------------------------------+ | A recursive check_host() result | Causes the "include" mechanism | | of: | to: | +---------------------------------+---------------------------------+ | pass | match | | | | | fail | not match | | | | | softfail | not match | | | | | neutral | not match | | | | | temperror | return temperror | | | | | permerror | return permerror | | | | | none | return permerror | +---------------------------------+---------------------------------+
