Sieve script: vacation auto reply is incomplete

[ybc37]

The vacation sieve script documented here (https://github.com/Uberspace/manual/blob/main/source/mail-filters.rst) is missing the definition of the variable subjwas. Should be something like this:

require ["variables", "vacation"];

if header :matches "Subject" "*" {
  set "subjwas" "${1}";
}

vacation
  # Reply at most once a week to a same sender
  :days 7
  :subject "Out of office: ${subjwas}"
"I'm not in the office from 20 May until 31 May.

Best regards
Jane Doe";
# The command "keep" is executed automatically, if no other action is taken.

Diff:

-require ["vacation"];
+require ["variables", "vacation"];
+
+if header :matches "Subject" "*" {
+  set "subjwas" "${1}";
+}

 vacation
   # Reply at most once a week to a same sender
