Message-ID header in Email

My QNAP NAS, TS-1273U-RP running QTS 5.2.10.3577 Build 20260731, sends Emails to notify various events. This is great, however, the email doesn’t include MESSAGE-ID header. The Email server I am using rejects such an email without MESSAGE-ID header.

While I understand MESSAGE-ID field is not a mandatory, adding it may cause no harm. I’d appreciate QNAP development team may consider to change in future QTS/QuTShero releases.

Thanks for your request! I’ll forward it to our internal team for evaluation. Could you also let us know which mail server you’re using, so we can look into this further? Thanks!
