sieve filter not working -- wildcard missing

[Martin Johannes Dauser]

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 at 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.

Greetings
Martin
