Question:

Mail-header Message-ID with spaces possible?

Mar 24 '15 at 10:31

Is it possible to add a message-id for email that has spaces in its name? In general I see message-id's that have no spaces. Just curious to know if it would work.

Accepted Answer

Message-ID cannot have spaces, it's a clearly defined header as per the RFCs for internet mail.
