Gmail spam and POP3

[Fernando S.]

Did anyone ever figure a way of marking messages as SPAM so that desktop clients can recognize them and put them in the correct folder? I've set gmail so that it puts spam messages in inbox folder, so I receive them, problem is I want to receive them somehow identified so the desktop client I use can move them to the correct folder. It would be so easy if gmail allows to put the marker name in the subject field of received emails.

If you are using IMAP, you should be able to sync the SPAM "folder" and just move the messages there yourself.  Then the client will update the online which moves them to the folder.

As I've declared in the title, must be POP3, not IMAP.

POP3 is a one way protocol... the only signals it sends to the server are "I have read you", and "You can delete this when I disconnect".

The answer then, is no.

I don't think this has anything to do with IMAP.

I think Fernando wants to let Gmail decide what is and isn't Spam, but have them delivered to his client program anyway, and let the client program move Spam messages into ITS own Spam folder on his PC.  I think he doesn't need (or even want) Gmail to file those Spam messages with the Spam label; so there is no need to use IMAP.  On the Gmail side, everything goes into the Inbox.

What Fernando is asking for, is a way for Gmail to mark messages that it would have identified as spam, with an altered Subject line that has the word "Spam" in it.

Gmail doesn't ever alter the Subject line.  I suppose you could suggest it to Google, but at the moment they don't do that.

Furthermore, I think that if you have a filter in your Gmail account that keeps Spam from being filed as Spam, then you are essentially telling Gmail that those messages are not Spam.  Even if Google did alter the Subject line, that wouldn't happen to those messages because you are calling them NOT spam.

If one is going to use a protocol that is designed so that all message filtering is done on the local PC and not on the server, i.e. POP3, then one must expect to have to manage Spam filtering there also.​

​I wouldn't want Google to modify my messages, especially the false positives (Spam) other than perhaps adding a spam score in the headers e.g. something like X-Gmail-Spam-Score: but certainly not the subject.

Andy, you've got it.

[Fernando Scussel]

Marko, to me doesn't matter if it's in the subject or in the header, like you've said (i didn't know it was possible). As far as there's a mark that the email client can recognize, all they would have to do is write a code that would detect that mark and put the messages in the spam folder. Very easy to code indeed. But as far as I know, there's nothing like that in the market.

[Zack (Doc)]

Easy enough to code, but you're looking for a service that no e-mail provider I know of provides, but there are people who provide that type of service.

When you tell your e-mail provider (in this case, Google) to not mark a message as spam, you're effectively turning off their spam detection.  If they're no longer detecting, then how could they mark.  There are online e-mail inspection sites that could receive your message and give it a spam score, but then you'd still need a way for that score to be delivered to you without your mail carrier using their spam filter, or that score, to move it out of your inbox.

The most effective way I could imagine would be to let your carrier do their own spam filtering, and use a protocol that recognizes folders, so you can pull the messages that they've marked.  I've already suggested this, but as you pointed out, you've rejected this option prior to even posting.

The only way I can see you using a 26 year old protocol (RFC 1081) that was designed only for downloading messages in a single mailbox, is to disable your online mail provider's detection so it's all in one box (you've already done this), and do 100% of your spam detection on your client.  This is possible to have SMTP servers submit messages to online evaluators who will give you back a score, but it's still 100% on your client to determine if it's spam, Google's detectors have already been disabled by your process.  SpamAssassin is one such evaluator.

[Fernando Scussel]

Zack, no need to disable gmail spam detection, you just create filter with the code: "is:spam". Then you set to not send to spam folder. Very simple.

[Zack (Doc)]

You're not understanding... When you do that,  you are signalling Google's learning spam filter that those messages are in fact, Not Spam, effectively disabling it's detection method.  There is no way to 100% disable it, but by having a filter take everything "in:spam" and moving it to inbox, you are effectively disabling it.
