ああ！これを踏まえて、再度調査したところ…結局、私たちの問題であることがわかりました。
上記で投稿した生のメールから、IncomingEmail.rawが実際には生のメールを保存していないことを発見しました…私たちはそれをEmail::Cleanerで加工しています。
これはRubyのmail gemのせいだと思われます…メールメッセージを書き出す際にパーツを並べ替えるようです。
[1] pry(main)> m = File.open('test.eml').read;
[2] pry(main)> Mail.new(m).parts
=> [
#<Mail::Part:39680, Multipart: true, Headers: <Content-Type: multipart/signed; boundary="Sig_/gizYC_1dGsAzUHvksdaMIe2"; protocol="application/pgp-signature"; micalg=pgp-sha256>>,
#<Mail::Part:39700, Multipart: false, Headers: <MIME-Version: 1.0>, <Content-Type: text/plain; charset="us-ascii">, <Content-Transfer-Encoding: 7bit>, <Content-Disposition: inline>>
]
[3] pry(main)> Mail.new(Mail.new(m).to_s).parts
=> [
#<Mail::Part:39720, Multipart: false, Headers: <MIME-Version: 1.0>, <Content-Type: text/plain; charset=us-ascii>, <Content-Transfer-Encoding: 7bit>, <Content-Disposition: inline>, <Content-ID: <6966b4914df79_31d5b1d38126@mars.mail>>>,
#<Mail::Part:39740, Multipart: true, Headers: <Content-Type: multipart/signed; boundary="Sig_/gizYC_1dGsAzUHvksdaMIe2"; micalg=pgp-sha256; protocol="application/pgp-signature">, <Content-Transfer-Encoding: 7bit>>
]
これにより、次の問題が発生します。
[38] pry(main)> puts Email::Receiver.new(m).select_body[0];
=> We received a court order to preserve the data on the system and were
=> forbidden from informing the system owner, which was awkward since
=> they had informed the system owner...
Which data did they request?
=> Since then I've always run my exit on a separate system on it's own
=> IP so if there were a legal demand to turn over "the system" it would
=> really only be that system. I'm not a lawyer but I don't think docker
=> provides enough isolation for that.
Can they deny you to turn the relay off?
If so, you could then operate a new "system" on another IP.
[39] pry(main)> puts Email::Receiver.new(Mail.new(m).to_s).select_body[0];
