Library containing Email related implementations in Elixir : dkim, spf, dmark, mimemail, smtp

MimeMail

Use MimeMail.from_string to split email headers and body, this function keep the raw representation of headers and body in a {:raw,value} term.

Need more explanations about pluggable header Codec...

MimeMail.to_string encode headers and body into the final ascii mail.

FlatMail

Flat mail representation of MimeMail is simply a KeywordList where all the keys [:txt,:html,:attach,:attach_in,:include] are used to construct the body tree of alternative/mixed/related multiparts in the body field of the MimeMail struct, and the rest of the KeywordList became the header field.

MimeMail.Flat.to_mail(from: "me@example.org", txt: "Hello world", attach: "attached plain text", attach: File.read!("attachedfile"))

|> MimeMail.to_string

DKIM

[rsaentry] =  :public_key.pem_decode(File.read!("test/mails/key.pem"))

mail = MimeMail.from_string(data)



mail = DKIM.sign(mail,:public_key.pem_entry_decode(rsaentry), d: "order.brendy.fr", s: "cobrason")

case DKIM.check(mail) do

  :none      ->IO.puts("no dkim signature")

  {:pass,{key,org}}      ->IO.puts("the mail is signed by #{key} at #{org}")

  :tempfail  -> IO.puts("the dns record is unavailable, try later")

  {:permfail,msg}->IO.puts("the sender is not authorized because #{msg}")

end

DMARC

Organizational Domain implementation using public suffix database : (https://publicsuffix.org/list/effective_tld_names.dat)

"orga2.gouv.fr" = DMARK.organization "orga0.orga1.orga2.gouv.fr"

SPF

Full implementation of the Sender Policy Framework (https://tools.ietf.org/html/rfc7208).

case SPF.check("me@example.org",{1,2,3,4}, helo: "relay.com", server_domain: "me.com") do

  :none      ->IO.puts("no SPF information")

  :neutral   ->IO.puts("nor authorized neither not authorized")

  :pass      ->IO.puts("the sender is authorized")

  {:fail,msg}->IO.puts("the sender is not authorized because #{msg}")

  :softfail  ->IO.puts("not authorized but don't be rude")

  :temperror ->IO.puts("temporary error, try again latter")

  :permerror ->IO.puts("spf error, ask to remote admin")
