My work uses e-mail lists extensively for internal communication. I'm running mailbox size limits, so I'd like to know what are the best lists to filter and delete.
I know I can view the sizes of individual e-mails (in the classic view, by going to
Size), but that isn't reflective of the total size of messages from a particular e-mail list (i.e. 10,000 messages of 10 KB each are bigger than a single 10 MB email.)
Is there a clever way to do this?
