Отправляю письмо с одного компьютера из 1С и из Thunderbird через SMTP. Настройки идентичные. Но у получателя от 1с приходит письмо без подписи dkim, а от Thunderbird dkim есть. Можно как-то воздействовать  со стороны 1с на это, т.к. на стороне сервера не очень понятно как это настраивается? :)

Думал это 1с кривой и не может работать с dkim. Но нет, если из 1с отправить письмо используя smtp gmail, то dkim там корректно добавляется.
