I have had a look round the forum and cannot find an answer so hopefully you can help.
Firstly I have to say that emails sent from Manager and using custom SMTP server work ok. I have had reason lately to test how good my server email settings are using ‘www.mail-tester.com’. Sending an email to mail-tester.com from Manager resulted in a good score but identified that there was:
“SpamAssassin Rule: MISSING_MID” Standard description: Missing Message-Id: header
This suggests that the mail was sent by badly-configured mailout software rather than by a normal email client.
I have checked other systems on my server that send emails and all arrive with a Message_ID ok. Is this a Manager issue? Is there any way to include this. I am using version 17.7.14 but just updated to current version and still the same.
Appreciate any thoughts on this.
