Modifying the email subject

[Robert_K]

Hello,

It is possible to modify the subject of all incoming messages by adding the prefix [external] to them ?

Hello,

Yes, it is. You might use this example https://www.root42.de/blog/?p=87 and adjust it for your case:

# Exim filter
if "$h_to:" matches Nroot@.*.your.domain.deN then
   headers add "New-Subject: [System] $h_subject:"
   headers remove subject
   headers add "Subject: $h_new-subject:"
   headers remove new-subject
endif

p.s. This is an example, though it has valid lines for exim configuration, the files and paths specified in the guide are not suitable for servers with DirectAdmin.
