I can see how this might be a concern with a large email setup, but with a large email setup, I wouldn't be hand-editing regexps in the Exim config.

I think you need to stop placing these special rules directly in the Exim configuration, and instead use a filtering system. For instance, you can create spam filters with SpamAssassin (https://github.com/Exim/exim/wiki/SpamAssassin), or you could use Sieve filtering (https://www.exim.org/exim-html-current/doc/html/spec_html/filter_ch-sieve_filter_files.html). I expect that both of these will be easier to relate to, and you don't have to reload the Exim configuration (and maybe break all of your email config). SpamAssassin can also test its own config to see if it validates, before you restart spamd (or similarly reload the config). -- Jan -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/

Do you have the main configuration setting "headers_charset = ISO-8859-1"? If your configuration file editor also uses ISO-8859-1 you could just enter the character. (or you use use utf-8 both places, that would work too) Your regex should probably say "video\\?" instead of "video?" that's probably why it's not matching. -- ت -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
