Here's a good article on this topic of using IMAP's search to find gift cards: https://krebsonsecurity.com/2021/09/gift-card-gang-extracts-cash-from-100k-inboxes-daily/
 
Apparently if we could search our IMAP logs we would be able to find signs of this activity ... but I don't think Surgemail (by default) retains a verbose log of all the IMAP activity, which would be a lot.

Is there a way that just IMAP SEARCH activity could be verbosely logged?
