[Rspamd-Users] Regex in Multimap does not work

[Andreas Wass - Glas Gasperlmair]

i did a few tests and in this article
https://rspamd.com/doc/modules/multimap.html#regexp-maps
is a link to

http://intel.github.io/hyperscan/dev-reference/compilation.html#pattern-support
and below "Supported Constructs" are also anchors ^ and $

so why does these expressions not matching to following line

Subject: Re:

/Subject: Re:\z/ MY_OWN_SYMBOL:8
or
/Subject: Re:$/ MY_OWN_SYMBOL:8
or
/^Subject: Re:$/ MY_OWN_SYMBOL:8

the following applies, but also if there is something after Re:

/Subject: Re:/ MY_OWN_SYMBOL:8

So, how can i match strings with rspamd, ending with in this case "Re:" ?

best regards, Andi
