Gmail popularized plus addressing which is a simple rule that ignores everything after a plus sign in the local part of an email address.

For example, messages sent to john+shopping@doe.com land into john@doe.com.

This behavior is built into Migadu and no additional configuration is required for it. In addition, we will auto-create a folder with the label given after the plus sign (e.g. shopping) and sort the respective message there.

For an alternative to plus addressing, take a look at subdomain addressing.
