Hi! You forgot the wildcard '.*' (= Match zero or more instances of any single character, except newline)
require ["regex"]; # rule:[test] if header :regex "from" ".*info$" { redirect "su...@domain.com"; } With this rule, you are filtering emails from toplevel domain '*.info' or new domains that might occur in future (e.g '*.superinfo'). If you want to restrict to classic tld '*.info' change the regex to ".*\.info$" The draft lists a table of common regex in section2: https://tools.ietf.org/html/draft-murchison-sieve-regex-08#section-2 There are online regex checker like https://regex101.com thought not specific to sieve's regex, which can be used to test your regular expressions. Sieve's regex are quite standard though.
