Hi,

For anti-spam settings, I’m trying to find out how to add the “List-Unsubscribe” header in Exim config.

I’ve been looking in Internet and in Exim.org site but haven’t found yet a tutorial…

Anyone knows how to do it?

Thanks for any advice.

Best regards,
Roberto Jobet

Extra headers like ‘List-Unsubscribe’ is not a function of the email server (exim4) but of the sending software. Ex: See php mail function here or PHPMailer library here

Hi @Lupu,

Thanks for your feedback!

As far as I know ‘List-Unsubscribe’ header should be set on the server.

Before Exim I was using Postfix, and it’s quite easy to setup: see here in " How it works: unsubscribe implementation methods" (https://blog.mailtrap.io/list-unsubscribe-header/)

Furthermore I’ve found an old post about Exim… https://saeedrahhal.wordpress.com/tag/exim/ where the author says to setup the “headers_add” directive in Exim’s config file (but unfortunately Exim has several config files…)

Best regards,

You can add headers in Exim, but you shouldn’t use that for unsub links. Wrong tool for the job.
