NAME ^

Mail::Decency::Policy::SPF

DESCRIPTION ^

A SPF implementation (http://www.openspf.org/) for decency based on Mail::SPF

Weight's incoming mail based on the sender policy framework.

The SPF suggests that your (sender) domain has an additional TXT record providing a list/range of server ip's which are allowed to send mails.

For an explanation of the spf result codes have a look here: http://www.openspf.org/SPF_Received_Header

CONFIG ^

    ---
    versions: [ 1, 2 ]
    
    # the sender ip is allowed to send from this ip
    weight_pass: 20
    
    # no spf support from sender domain
    weight_none: 0
    
    # it is a fail, but sender domain admin has not the balls to use hard restrictions
    #   neutral is a bit more wishy-washy then softail is, but essentially both
    #   are saying: the particular sender is not really permitted, but it won't deny it
    #   the ..by_default neutral status i don't get..
    weight_neutral: -10
    weight_neutral_by_default: -10
    weight_softfail: -10
    
    # this admin has the bals. the sender ip is not permitted for this domain
    weight_fail: -50
    
    # some temporary dns problem. should not be weighted negativly, cause this
    #   could happen to any of us
    weight_temperror: 0
    
    # the permanent error says: we received something, but dont know what.
    weight_permerror: -10
    
    # this seems to catch error's which could not be further determined..
    weight_error: 0

CRITICS

Critics say the SPF could break existing structures, eg you cannot send mails from gmx.com via your company's mails server. Advocates reply: that's the idea and it is good.
