Trash cleared messaged older than 7 days

[squarebox]

Since a while i have noticed mails in the Trash are removed from the roundcube server.
Recently i noticed that mails older than 7 days are removed or purged.

I dislike this feature because sometimes i need to recall a message from the Trash folder, in order to see what someone has written in the past.

I looked at some logs but could not trace any errors therefor i think its a setting.
Further more i rulled out any hardware clients (pop/imap) that might have an auto-archive setting.

I have a dedicated centos server running roundcube by default settings.
Roundcube Webmail 1.0.0
Installed plugins
markasjunk2      GPL-3.0   
password   3.4   GNU GPLv3+

that is not a feature of roundcube. In my experience, this is generally caused by a setting on a mobile device, most commonly an iPhone/iPad that has been configured to access the same account.

thank you for the reply, it should be easy to tackle because only one person uses that account
i will change the password of that account and see if a tablet, mobile or outlook is causing it

Update: its has been a while and i have disabled the mailboxes synchronization on Android and Outlook 2013 (PC).
I found out that this is OK and trash folder is still full and was not cleaned up any more.

If i would enable Outlook 2013 or Android again the trash mailbox was cleaned up again.

I double checked and Outlook 2013 and auto-archiving is disabled.
I cant really find a Android setting that is related with auto-archiving.

Anyone some suggestions?

I think its a Google Bug because i found this thread about Email retention within Google Admin Console that manages Main App

The solution was this.....
https://yeri.be/courier-imap-and-auto-deleting-trash-after-7-days


Open the courier-imapd config file:

sudo vi /etc/courier/imapd

And just comment out the line that contains EMPTY_TRASH like it discribed in the link above

# IMAP_EMPTYTRASH=Trash:7,Sent:30

and optional

# IMAP_EMPTYTRASH=Trash:7
