Hi,
I'm using this library to send some html email with attachments, and there is issue when emails are sent to iCloud accounts.
The email content is pretty simple, html + pdf file.
However, emails are rejected by iCloud mail server.
The error iCloud mail server returns is (not much more explanation):
554 5.7.1 [CS01] Message rejected due to local policy. Please visit https://support.apple.com/en-us/HT204137
The culprit seems to be Message-ID header. Once it is present those emails are rejected.
For the test I sent a simple email via curl and then another one with Message-ID generated by the library, - the second email got blocked.
curl --ssl-reqd \
--url 'smtp://smtp.gmail.com:587' \
--user 'user:pass' \
--mail-from some@example.com \
--mail-rcpt <some>@icloud.com \
--upload-file - <<EOF
From: <some@example.com>
To: <some@icloud.com>
Message-ID: <GENERATED>
Subject: You are awesome!

Сan it be made optional/removed?
Thanks in advance!
