Hello, how can I block foreign charsets in rspamd? Like /Content-Type:.charset\s=\s*\“(koi8-r|big5|euc-kr|gb2312|ksc5601-1987|iso-2022-jp|windows-1251)\“/ I do this at present with pcre via Postfix main.cf mimeheaderchecks = pcre:$filter/mimeheaderchecks -- freundliche Grüße, Sincerely yours, Katharina Knuth
