[Rspamd-Users] Adding Message in First line of mail for External Mails

[Durga Prasad Malyala]

Hello all,

Any Ideas how can I add a line on top of mails like  below
 “External Email: Exercise caution when opening attachments or
clicking on links.”
 Preferably I want to add if there is a link/URL or attachment in received mail.

Regards
DP
