How to set Thunderbird to delete emails older than a certain year only from the local computer, without doing anything on the server?
Hi everyone, I set in Thunderbird synchronize the most recent 3 years mails. Unfortunately, I didn't see the setting that to delete the mails which older than 4 years from only local copy! (not delete on server!!!) I would like to solve this with Gmail IMAP settings. Can someone describe how to do this? Thank you in advance for your help. Balazs
