trigger sieve after redirect to achieve compliance to German law

[derStephan]

Hi,

I want to have a GoBD compliant setup where I put every incoming or outgoing mail into an archive.

The requirement is to make a copy of all inbound and outbound in a secure place in case you have to proove that you are not involved in corruption.

My approach is to have a sieve script at data stage:

The script in else makes a copy to another mailbox:

godb_mailweiterleitung:
redirect :copy "[email protected]";

The script with the condition should only run in the archive mailbox and flag the mail as seen.

gobd_mailablage:
require["imap4flags"]; setflag "\\seen";

The first one is running alright. But the one with the condition is never triggered. In fact, the redirect does not even show up in trace log. So I am assuming, that local redirect is not really an SMTP step. Is that correct?

Where can I trigger a sieve script after local redirect? Flagging the mail as seen is only the beginning, later it should sort mails into folders by year/month. And it should be deduplicated.

If I get this to work, I will happily share my results. Thanks in advance.
