Best way to use Gmail spam filter from within Apple Mail?

3) I used to use Spam Sieve, but a) I want a spam filter that will catch email not only before it reaches the InBox on my Mac, but also on my iPhone and b) if Gmail has this service anyway, I might as well take advantage of that without adding another layer of software to my computer.

Thanks in advance for your help!

I think you are missing the boat if you choose not to use your SpamSieve.app; by far the single best software I ever bought and use daily with 99.8% accuracy.

Gmail doesn't have much in the line of spam settings. Just let that be and control what you can from within Mail. If you have the provider filtering spam and Mail filtering spam, you may not know which is marking a message junk and won't know which to fix if you want to mark something as not junk.

1. If gmail marks a message as spam and moves it to the Spam folder, then it will reflect that in Mail.

If Mail marks a message as junk, then it will be moved according to the settings in Mail's Junk settings. Set Mail's Junk preferences to move spam to the Junk mailbox.

2. If something is marked as Spam and you don't want it to be, then you can mark it as not junk.

3. As per you 1st question, same applies to the iPhone. Junk mail should go to the junk mailbox. Set your mailboxes on the iPhone in the Advanced Mail settings for that account.

IMAP is used to sync mailboxes between devices. What is on the server will be reflected on the devices. If the server marks a message as spam, then it will go to the spam (Junk) mailbox and not the inbox.

Gmail does not have spam settings, but yes you can mark or unmark messages as spam.

I though the iPhone had mailbox settings for Junk, but it appears I made a mistake there. Maybe there was in the past, but there are none now. The iPhone should reflect what's on the server.

In the Mail application, you have to open up Mail preferences and set the Junk filter. Unless you plan to use webmail instead of Mail, set this and control Junk from within Mail. I don't thing it will teach gmail what is junk or not, but you won't have to go back and forth to the website to unmark or mark spam.

You can use gmail to filter spam, but you will most likely have to log into the webmail site to mark or unmark junk mail. I don't know if just moving a message to or from the spam mailbox for gmail in the Mail application will be sufficient enough to train the gmail server. You won't have a junk or not junk button and no database will be kept on the computer for it.

Point taken. Is there any way to get Spam Sieve to filter on the server side so I avoid spam on my phone, too besides leaving my computer on and running and checking email?

Yes there is.

Granted, even if you are using IMAP your computer has to be up and running to service your iPhone if the Spam folder is located on your Mac. Maybe this is the crux of your problem.

You can install Spam folder server side

Here is a quick search, see if this helps:

In Mail, go to Preferences>Junk Mail and check this box:

If you click on spam box in web mail from server side for gmail account , it is deleted after 30 days or you can select the mails and manually delete .

And also can create rules to filter .
