Feature force unspam

[diroots]

proposition for feature request : https://github.com/the-djmaze/snappymail/issues/1510

• add a new sieve action : "Force Unspam" which basically creates a sieve filter like

{
    fileinto "INBOX";
    stop;
}

[diroots]

i could test this quickly, and could see in the mail server siece script folder a new entry created from web ui :

it seems it still has some labelling issues :

and action name in the dropdown :

but after saving in the UI, the sieve script was sent to mailserver for the user

There is more to it.

1. removeflag "$Junk";
2. addflag "$NotJunk"; OR
3. setflag "$NotJunk"; (which removes all other flags) OR
4. fileinto :flags "$NotJunk" "INBOX";

Same can be done for "mark as spam" and for "mark as phishing" ($Phishing)

Hello @the-djmaze should i continue and also add this flag too or this PR will not be merged as per your comments in initial issue already closed?

[the-djmaze]

I closed the issue because i removed the rainloop option to disallow fileinto INBOX and just allow it.

This PR can stay open so we can improve your suggestion as i mentioned regarding the flags.

So an option for "not spam" and "spam" should be improved with the flags.

This sort of broad filter would also affect systems where there are other destination folders for messages... For example I file my messages into subfolders based on local_part_suffix. Since I run Sieve filters after this step, the destination folder would be lost. Just something to consider.
