Question

Sending emails works perfectly for all major email clients, except for hotmail (and some other), it shows as:

=?windows-1255?Q?Z33=30_=F9=22=E7=20=F2=E1=E5=F8_=F9=E5=E1=F8=20=E1=F9=E5=E5=E9=20=36=30_=F9=22=E7=20=EC=22=EE=F8=E2=E5=E6=E4=22=2C_=E1=E9=FA_=F7=F4=E4=20=E5=EE=E0=F4=E9=E9=E4_=EE=F9=F4=E7=FA=E9=FA=2C=20=E1=EE=FA=E7=ED=20=F9=E5=F7=20=E4=F4=F9=F4=

Dosn’t matter if it’s utf8 or not. It seems like hotmail can’t read long quoted subjects, because for shorter ones it shows up ok.

AFAIK what gmail does for example is to split the subject to pieces, 64 (or something) chars long…
But I can’t figure out how to do that in rails (2.3.8).
Rails encodes the subject by default, in quoted form, can’t find how to override that so I could split it by myself…

Thanks.

This is what worked for me:

module ActionMailer
  module Quoting
    def quoted_printable(text, charset)
      require 'base64'
      #text.scan_utf8(/.{1,64}/m).map{|text| "=?#{charset}?B?#{Base64.b64encode(text)}?="}.join("\n")
      "=?#{charset}?B?#{Base64.b64encode(text).gsub(/\n/, '')}?="
    end
  end
end

module TMail
  class SubjectHeaderField < UnstructuredHeader
    def parse
      #Do nothing
    end
  end

  class HeaderField
    FNAME_TO_CLASS = FNAME_TO_CLASS.merge('subject' => SubjectHeaderField)
  end
end
