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.
