I'm basically doing a search on a email in the past 7 days and getting results with empty EMAIL_LOG_SEARCH_RECIPIENT. Doesn't give me anything useful.

for example the same user in the UI returns 30 + results, but doing this, return 7 but all empty receivers. basically i'm passing a filter filters: "EMAIL_LOG_SEARCH_SENDER==#{sender_email}",

So because I get nothing useful out of this, I believe it doesn't show any delivery status information.
