• Hi there,

    I am testing my deliverability of my transaction e-mails with mail-tester.com.

    Current setup: sending all mails from domain via post smtp server with sendgrid smtp server via API

    I am getting An Error stating that the message-id is nog correct. Is this message id created by the post SMTP plug-in?

    If I compare the message ID to other mails I receive, it seems that the message id is without brackets < and >
