Can I modify email headers in an IMAP folder?

Question

My email provider anti-spam system adds a tag before the subject of emails when it detects spam or viruses.

It looks like *** PROBABLY SPAM *** What a night we had !

It's not very accurate and results in many false positive tags.

I archive some emails (like the one in the example) and these tags look dirty.

Do you know a way to get rid of them occasionally, without disabling the filter on the server ?

Thank you,
Stéphane.

Not directly, but you can download the messages, process them, and upload them back to IMAP folders. Any good IMAP client will let you do that.
