Dear Sébastien,

great that now a roadmap is available for SoGo and 0006013 is solved. I checked the roeadmap for upcoming 5.12 and was wondering about this ticket 0006023.
By whom of the community was this problem raised and to solve which problem?
@all readers: Do you need such a function and for what?

Our opinion: In a business environment there are (European) rules that mails have to be kept for 6 years at minimum and 10 years if related to financial matters (see https://commission.europa.eu/law/law-topic/data-protection/reform/rules-business-and-organisations/principles-gdpr/how-long-can-data-be-kept-and-it-necessary-update-it_en for more information).
And we are forced by law to follow this regulation.
So please make this function configurable in the admin configuration so that we can switch it off for all SoGo users for mails younger than X years.

Thank you an best regards.

The Bahnkonzept team from Dresden/Germany

The feature has been merged in this commit and in nightly build NB 20241121.

To use it, just use the Clean folder... contextual menu (3 vertical dots) on the folder / or the mailbox.
@bahnkonzept you can use SOGoDisableMailCleaning = NO; if you want to disable this.
