Emails deleted in the trash folder

[smaugain]

Hello,
Is it possible that EGroupware automatically deletes messages from the trash folder?
I find that without deleting messages in my trash, the total number of messages decreases.
I’m using the up-to-date Docker on a courier-imap server. I don’t use any email client other than Egroupware on PC and mobile. No other user is logging into my account.
Thank you in advance.

Hi Silvère.

Is it possible that EGroupware automatically deletes messages from the trash folder?

No.

I have something like that on my wish list. But with a low priority.

If it is OK for you to delete the trash completely, including the most recently deleted mails, you can also do this from the context menu:

Thanks Stephan,
I’m not asking for a feature to be added, I just want to know the reason for deleting messages from the trash. I will try using a new email client to see if the problem persists. Maybe it’s from my imap server.

Ah, OK. I had understood that differently.

Well then:
A clear no. EGroupware does not delete emails by itself (automatically).

I only know something like this from email providers that do it automatically. Sometimes they just switch it on without asking. But you can usually switch it off again.

But you seem to run your own mail server…

Yes, I use my own mail server. I will temporarily use another mail client to clear Egroupware.
Thanks

Hi,
It took me a while to understand, but I now know the exact reason for the problem.
It is in fact courier-imap which automatically deletes mails from the trash depending on their age. But what I didn’t understand was the erasure criterion, it uses CTIME and not MTIME to get the date it was moved to the trash.

cat /etc/courier/imapd | grep EMPTYTRASH
IMAP_EMPTYTRASH=Trash:7

This option allows you to automatically delete mails moved to the trash 7 days ago.
Sorry for the noise.
