Beware that LTS support for jessie ended in June 2020. https://www.debian.org/releases/jessie/ That system should be upgraded to some release with security support as soon as possible, especially since it's dealing with e-mail as far as I understand from your other messages.
Well, ending LTS support for jessie was one of the reasons for considering upgrade 8 to 9. However, in any case it is a single-purpose machine where most of activity is 'unconnected'. Furthermore, the comp is behind the firewall where almost all in & out activities are banned.
Related to e-mail security: That box stores & forwards amateur radio traffic only, where the local users access their mailboxes by ham radio stations, not by the Internet. The Internet is used just for server-to-server batch exchange, where partnering servers are licensed and proven.
(And all of that is plain text only. No html, no scripts ... An advantage of ham radio vs. Internet :-)
