My email provider uses roundcube for webmail. They also have very poor filtering for junk so I do find wanted emails in my junk folder.
I set these to "not junk" and they are moved to the inbox. So far, so good.
My email client is emclient and when I download email, the no longer junk emails are put in the junk folder. Looking at the headers, the x-spam attribute is set to yes.
When the email is moved from junk to Inbox via webmail, shouldn't the header be set to no or removed?
Roundcube doesn't change the mail headers when the email is moved to the inbox.
But could it? Should it?
Could it?
- No the IMAP spec doesn't allow for messages to be edited, technically you would have to delete it and create a new email without the headers in its place.
Should it?
- I don't think it should, that header should stay in place as a record of how the mail server processed the email, it would be useful if debugging the system as well. I've never seen a system that removes the header when setting a email as not junk.
