sendmail заменяет HTML-тег [длинные строки в сообщениях электронной почты]

/ 12 октября 2018

Я использовал sendmail, чтобы отправить электронное письмо ниже к квитанции.Как ни странно, один из тегов html был заменен, как только я его получил.Таким образом, таблица выглядит нелепо.

Кто-нибудь знает, что происходит?

Используемая команда: 

sendmail -t -f "test_mail@${HOSTNAME}" < /tmp/test_mail

Обновление: добавление новой строки в конце каждого тега html решило проблему,но почему??

Содержимое / tmp / test_mail 

to: xxx.xxx@outlook.com

ДЛИННЫЕ строки в сообщениях электронной почты (SMTP RFC821 / RFC5321)

Диагностика:

Sendmail (by sendmail.org) разрывает длинные строки в сообщениях электронной почты.Другие MTA / SMTP-серверы могут вести себя аналогично.Ограничение Sendmail составляет 990 байт на строку.

В вашем случае самая длинная строка длиной 4560 байт была разбита на строки 991, 991, 1977, 604 байта.

Рекомендуемые исправления:

Не используйте длинные строки в вашем html-шаблоне
ИЛИ
Передайте сгенерированный html через tidy (программа форматирования html)
ИЛИ
кодирует тело сообщения как печатаемое в кавычках (оно заботится о слишком длинных строках)
Для этого требуются дополнительные заголовки. Кодирование в печатаемых кавычках также удобно для почти кодировок ASCII (обычно ASCII /американо-английский плюс несколько дополнительных / специальных букв)

RFC5321 4.5.3.1.6 Текстовая строка

4.5.3.1.6.Текстовая строка

Максимальная общая длина текстовой строки, включая <CRLF>, составляет 1000 октетов (не считая начальную точку, дублированную для прозрачности).Это число может быть увеличено за счет использования SMTP-сервисных расширений.
