Informations about the package tls_icon
Roundcube TLS Icon
Displays a small icon after the subject line that displays the (presumed) encryption state of received mails. This plugin parses the "Received" header for the last hop and checks if TLS was used. This requires TLS logging in the receiving MTA.
In Postfix this can be enabled by
setting smtpd_tls_received_header = yes
. Sendmail
should work out of the box. Other MTAs have not been explicitly tested.
Note that while this talks about "encryption", this does not imply security. An encrypted mail may still be insecure, mostly because mailservers generally use "opportunistic TLS", where MITM attacks are possible. This also only validates the last hop of an email - some emails may run through multiple hops and we don't know anything about the security of these.
