Случайни проблеми с връзката с Amazon SES

Наскоро започнах да използвам Amazon SES. Първият ми опит беше да използвам порт 25, но имах много проблеми с връзката. След известно търсене открих, че EC2 дроселира трафика на порт 25, за да избегна нежелана поща, така че промених на порт 587, но от около 1000 ежедневни имейла, около пет пъти получавам изключения за SMTP връзка в моето приложение.

Смятам, че е случайно, защото няколкото неуспешни имейла са в различни части на приложението и не открих никакъв модел между тях.

Моята квота за изпращане е 10 000 и в имейлите има по-малко от 50 получатели. Нормално ли е понякога изпращането да е неуспешно?

Благодаря предварително.

Използвам apache commons email 1.3.2 със следните настройки:

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);

Изключения:

Трябва да сте сигурни, че не превишавате ограничението за изпращане и скоростта на изпращане - звучи сякаш сте в рамките на квотата за изпращане, но може би надвишавате разрешената скорост на изпращане:

  • Квота за изпращане—Максималният брой имейли, които можете да изпратите за период от 24 часа. Квотата за изпращане отразява текущ период от време. Всеки път, когато се опитате да изпратите имейл, Amazon SES проверява колко имейла сте изпратили през предходните 24 часа.

  • Максимална скорост на изпращане—Максималният брой имейли, които можете да изпратите в секунда. Можете да надвишите това ограничение за кратки изблици, но не и за продължителен период от време.

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

Освен това изглежда, че казвате, че понякога имате 50 +/- получатели, изброени в един имейл. AWS SES препоръчва да ограничите имейлите си до един получател.

Благодаря за отговора. Редактирах въпроса си толкова много пъти, че забравих да сложа, че приложението ми изпраща около 2000 имейла дневно, така че квотата е наред. Съгласен съм за единичния получател по имейл, но трябваше да оптимизирам процес, който изпраща до 1500 имейла последователно. Според документацията лимитът на получателите е 50, така че изпращането на партиди от 50 прави процеса много по-бърз. Реших тези проблеми с връзката с помощта на smtps, ще напиша отговор, за да го опиша по-добре. - person FkJ; 17.12.2013

Проблемът е решен чрез използване на SMTPS с порт 465.

Commons Email изглежда не се справя добре със SSL, тъй като isSSL винаги се показва като false в режим на отстраняване на грешки. Така че отмених метода за изпращане от HtmlEmail:

@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);
            }
        }
    }
}
