=== Hello ドメイン
=== HELO ドメイン
SMTP ではメールを送る側のホストの名前を要求されるのですが、
ダイヤルアップなどの場合には自分のマシンに正式な名前がない場合が
あります。そのような場合は適宜 SMTP サーバの名前などを与えてやら
ないと配送を拒否されることがあります。SMTP.start あるいは SMTP#start

SMTP ではメールを送る側のホストの名前 (HELO ドメインと呼ぶ) を要求
されるのですが、Net::SMTP ではとりあえず localhost.localdomain と
いう名前を送信しています。たいていの SMTP サーバはこの HELO ドメイン
による認証はあまり真面目に行わないので (簡単に偽造できるからです)
問題にならないことが多いのですが、まれにメールセッションを切られる
こともあります。そういうときはとりあえず HELO ドメインを与えてみて
ください。もちろんそれ以外の時も HELO ドメインはちゃんと渡すのが
ベストです。
HELO ドメインは SMTP.start/SMTP#start の第三引数 helo_domain に指定
します。

=== Giving "Hello" Domain

If your machine does not have canonical host name, maybe you
must designate the third argument of SMTP.start.
In almost all situation, you must designate the third argument
of SMTP.start/SMTP#start. It is the domain name which you are on
(the host to send mail from). It is called "HELO domain".
SMTP server will judge if he/she should send or reject
the SMTP session by inspecting HELO domain.
