最近、Amazon SES を使い始めました。私の最初の試みはポート 25 を使用することでしたが、多くの接続の問題がありました。いくつか検索した結果、EC2 はスパムを避けるためにポート 25 のトラフィックを抑制していることがわかったので、ポート 587 に変更しましたが、毎日約 1000 通の電子メールから、約 5 回、アプリケーションで SMTP 接続の例外が発生します。

失敗したいくつかの電子メールはアプリケーションのさまざまな部分にあり、それらの間にパターンが見つからなかったため、ランダムであると考えています。

私の送信クォータは 10000 で、メールの受信者は 50 人未満です。たまに送信に失敗するのは普通ですか？

前もって感謝します。

次の設定で apache commons email 1.3.2 を使用しています。

setCharset("UTF-8");
setHostName("email-smtp.us-east-1.amazonaws.com");
setFrom("..."); // email from a verified domain
setAuthentication("...", "..."); // amazon smtp credentials
setSmtpPort(587);
setStartTLSEnabled(true);
setStartTLSRequired(true);

例外:

送信制限と送信レートを超えていないことを確認する必要があります。送信クォータ内にあるように聞こえますが、許可された送信レートを超えている可能性があります。

  • 送信クォータ— 24 時間に送信できるメールの最大数。送信クォータはローリング期間を反映しています。E メールを送信しようとするたびに、Amazon SES は過去 24 時間に送信した E メールの数をチェックします。

  • 最大送信レート— 1 秒あたりに送信できる電子メールの最大数。短いバーストの場合はこの制限を超えることができますが、持続的な期間は超えられません。

http://docs.aws.amazon.com/ses/latest/DeveloperGuide/manage-sending-limits.html

また、1 つのメールに 50 +/- の受信者がリストされている場合があると言っているようです。AWS SES では、E メールを 1 人の受信者に限定することをお勧めします。

ポート 465 で SMTPS を使用して問題を解決しました。

isSSL はデバッグ モードでは常に false として表示されるため、Commons Email は SSL を適切に処理していないようです。そこで、HtmlEmail の send メソッドをオーバーライドしました。

@Override
public String send() throws EmailException
{
    buildMimeMessage();

    // Implementação padrão de send() não conecta corretamente via SSL
    Transport transport = null;
    try
    {
        message.saveChanges();

        transport = getMailSession().getTransport("smtps");
        transport.connect("email-smtp.us-east-1.amazonaws.com", 465, <<amazon SMTP username>>, <<amazon SMTP pasword>>);
        transport.sendMessage(message, message.getAllRecipients());

        return message.getMessageID();
    }
    catch(MessagingException e)
    {
        throw new EmailException(e);
    }
    finally
    {
        if(transport != null)
        {
            try
            {
                transport.close();
            }
            catch(MessagingException e)
            {
                throw new EmailException(e);
            }
        }
    }
}
