I target system has a column named msg Id, the data in it was created by adobe campaign when sending email to the system, the data is like NM60002D2AC001D1A16abcdtest@myemail.com. Is anyone know how does the data created by AC, and where can I find it? Thanks!
The message-ID is assigned by the campaign MTA while sending the message as an SMTP email header and is unique for each recipient. It is generated based on an algorithm which is present in the server side code.
This is generated in runtime by MTA and does not persist in the database to be retrieved later or viewed.
The message ID is a global standard for mailing systems and is documented here :
