Currently it is possible to add an AOL based email address to Spamdrain using oauth2 standard where you will just need to authorise Spamdrain to access your email address with no need to enter the password. Once you enter an AOL based email address during sign up / adding email address you will see the prompt on how to proceed. Please follow the steps in order to authorise Spamdrain.
In case you are still experiencing issue with your mail when Spamdrain can not connect to your email server, you could use the app specific password solution. In order to do that please refer to the following guide:
Once the app specific password is create you can update the settings with that password and the filtering will be resumed (you may need to click on play icon if the filtering is paused).
If you need to add AOL email address please refer to the guide above and create an app specific password that will be used during email address adding as a password.
If there is an issue you are still experiencing please contact our support and we will gladly assist you.
