dovecot - Jan 2019 - Discard mail with from date older than xxxx

I know that sieve doesn't do math. The file would be created externally.

Based on examples in section 4.4 of
https://tools.ietf.org/html/rfc5260#section-4

I figured something like this would work.

if date :value "le" :originalzone "date" "date"
"2018-10-25" {
??????? fileinto "SPAM";
??????? stop;
}

However, I get the following.

spam: line 41: error: unknown tagged argument ':value' for the date test
(reported only once at first occurrence).
spam: error: validation failed.
sievec(root): Fatal: failed to compile sieve script 'spam.sieve'

Does anyone have any advice on how to get this working?

Thank you.

Trever

Hi Trever

here is a snippet I use occasionally:

if allof(
currentdate :zone "+0200" :value "ge" "iso8601"
"2017-09-04T00:00:00+02:00",
currentdate :zone "+0200" :value "le" "iso8601"
"2017-09-06T18:09:00+02:00"
)

Please, correct me if I am wrong. This looks at the system clock. I need
to look at the date in the email (Date header). I am trying to catch
spam that hides 6-9 months in the past (in the last week I have had two
from August 2018 show up... obviously forged header, but...).

Thanks.
