Scott, you are right. And I guess it's computed faster too.

# rule:[test] if header :matches "from" "*.info" { redirect "subbs@domain.com"; }

Even a TLD like "*.superinfos" may be included: "*@*.*info*"

Why do you use regex ?

You can just use matches: https://p5r.uk/blog/2011/sieve-tutorial.htm l#matchtype

It's not being honored; all emails from .info TLD ends up in the inbox and none are redirected. Let me know what I'm doing wrong.

Thanks.

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 "subbs@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$"

Oh, and if you want to include a TLD like "*.superinfos" The regex needs to be

".*\..*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.
