There are several options for handling spam and junk emails.

1) There is a swipe action to remove spam emails called 'Spam'. When you swipe over an email and tap on the Spam button, AltaMail will block that email sender and move the email to the Spam folder.
Use the swipe settings to change the 'Spam' swipe actions. View

2) Spam rules are available to mark emails as spam and also automatically move spam emails to the spam folder. Tap on the button in the bottom right of the screen with four boxes. Then tap on the 'Spam Filter' button to show the Spam rules. You can then turn these rules on or off and also edit their settings.

When you first use AltaMail the spam rule will only mark emails as spam with a flag. 🚫 You can also tap on this flag to edit the spam settings.

You can change the spam rule to also move suspected spam emails to the spam folder. Open the 'Spam Filter' screen and then tap on the 'Spam Detector' rule to edit it. Then turn on the 'Move to folder Spam' button.


Simple Spam Block List
The 'Simple Spam Block List' rule will process spam blocked email addresses for you. New emails with addresses in the spam block list will be moved to the spam folder automatically. Emails in the 'Known Senders', contact list and 'Spam Safe List' will not be marked as spam.


Spam Detector
The 'Spam Detector' rule will use a Spam detector to find Spam emails and process them. When AltaMail is first installed, the 'Spam Detector' rule will be enabled but it will only mark emails as suspected spam with a red flag. Tap on the red flag on an email to view and edit the spam settings. More


Not Spam
The 'Not Spam' rule can check your Spam folder and find any emails that should not be there. If there are emails from the 'Spam Safe List' and the 'Known Senders' lists in the Spam folder then this rule will move them back to the Inbox folder. You can turn this rule on and off in the email rule list screen.
This rule will run when new emails are received in the Spam folder, usually each time you open it. You can manually open and refresh the spam folder or you can set up the spam folder to refresh automatically in the background using the 'Auto check email folders' setting. Details
This rule is useful for accounts like Yahoo and Gmail which have their own spam filters but may mark emails from your contacts and known senders as spam in error.
