I've Dovecot and dovecot-sieve v 2.2.27 installed on a Debian 9.6. I'm
trying to set a Sieve filter which will redirect all emails from info
(i.e. .info) TLD to another email. This is the filter:
require ["regex"];
rule:[test]
if header :regex "from" "info$" { redirect "subbs@domain.com"; }
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.
Why do you use regex ?
You can just use matches: https://p5r.uk/blog/2011/sieve-tutorial.html#matchtype (https://p5r.uk/blog/2011/sieve-tutorial.html#matchtype)

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*"

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$" { redirect "subbs@domain.com"; }
With this rule, you are filtering emails from toplevel domain '*.info' or new domains that might occur in future (e.g '*.superinfo'). If you want to restrict to classic tld '*.info' change the regex to
".*\.info$"
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.

You should use the "address" test instead. This parses the header for addresses. Using the "header" test this way is unreliable. For example, an address wrapped in <...> is not handled well by your attempt.
So, this is better:
if address :matches :domain "from" "*.info" { redirect "subbs@domain.com <mailto:subbs@domain.com>"; }
