I subscribe to a number of mailing lists and, up until recently, had been using individual server-side rules to sort all incoming messages from those lists in to a specific folder. However, as the number of lists I was subscribed to grew, adding and maintaining individual rules became increasingly tedious.
To make managing messages from mailing lists easier, I’ve switched all of the mailing lists I subscribe to to an alias that is targeted at the specific folder I want them sorted in to. To set this up you need to create a new alias and target that alias at a specific folder using plus addressing as follows:
Now, instead of having to create a rule for each mailing list sender, I simply provide the alias that I have created and any messages received via that alias are sent directly to the folder I store mailing list messages in.
