[Rspamd-Users] block foreign charsets

[Katharina Knuth]

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
