It would help if you'd ask Q's rather than assume you absorbed all the context & details from a short requirements outline. The TMTP server supports replication to multiple clients per account, which enables backup. I note in the FAQ that servers may perform archiving (which is not the same as retaining all the traffic). Any network information system could be compromised. Zillions of them are trusted. If you're alluding to E2EE, see the FAQ. https://mnmnotmail.org/faq.html https://mnmnotmail.org/faq.html
