У меня есть код, который хорошо работает при использовании SMTP-сервера Gmail с моими личными учетными данными:
fun sendEventInvitation(from: Profile, to: Profile, meetup: Meetup) {
val message: MimeMessage = emailSender.createMimeMessage()
message.setFrom(InternetAddress("foo1@foo1.com"))
message.setRecipient(Message.RecipientType.TO, InternetAddress("foo2@foo2.com"))
message.subject = "foo"
val messageBodyEvent = MimeBodyPart()
val id = UUID.randomUUID().toString()
val eventIcs = formatCalendarFile(id, from, to, meetup)
messageBodyEvent.dataHandler = DataHandler(ByteArrayDataSource(eventIcs, "text/calendar; charset=\"utf-8\"; method=REQUEST"))
messageBodyEvent.setHeader("Content-Transfer-Encoding", "base64")
val multiPart = MimeMultipart()
multiPart.addBodyPart(messageBodyEvent)
message.setContent(multiPart)
emailSender.send(message)
}
eventIcs - это в основном String правильного формата iCal.
Но всякий раз, когда я переключаюсь на сервер Outlook, используя учетные данные компании, он выдает следующую ошибку:
554 5.2.0 STOREDRV.Submission.Exception:InvalidRecipientsException; Failed to process message due to a permanent exception with message A message can't be sent because it contains no recipients. InvalidRecipientsException: A message can't be sent because it contains no recipients. [Hostname=AM6PR01MB5011.eurprd01.prod.exchangelabs.com]
DEBUG SMTP: got response code 554, with response: 554 5.2.0 STOREDRV.Submission.Exception:InvalidRecipientsException; Failed to process message due to a permanent exception with message A message can't be sent because it contains no recipients. InvalidRecipientsException: A message can't be sent because it contains no recipients. [Hostname=AM6PR01MB5011.eurprd01.prod.exchangelabs.com]
Теперь, как ни странно, когда я удаляю заголовок вложения method=REQUEST:
messageBodyEvent.dataHandler = DataHandler(ByteArrayDataSource(eventIcs, "text/calendar; charset=\"utf-8\"))
Он работает, но поскольку этот заголовок отсутствует, ICS не очень хорошо распознается клиентом Outlook и не отображает параметры RSVP для получателей, как объяснено здесь .
Я пытался отправитьприглашение от Thunderbird с использованием тех же учетных данных, и оно работает.Так что это не ссылка на правила вообще.
Вот полный отладочный вывод:

Есть идеи, почему существует такое поведение?
