in reply to Thunderbird: Free Your Inbox • • •I've been wanting to switch to using one email client instead of several for a long time.
But the IMAP protocol is disturbing because if delete some messages from another place, then the main client will automatically delete the messages after synchronization. A mechanism similar to snapshots is needed.
