I'm using mail filters in Thunderbird that move emails to specific mail folders (IMAP). After filters have been applied and unread messages have been moved to the folders, I open my Android e-mail app (e.g. Bluemail), it synchronizes, but it doesn't show that there are new e-mails that are located in subfolders. Only after I opened the folder directly I see the "new email" counter next to the folder name.
Is there any mail app for android that notifies about new, unread e-mails in subfolders from IMAP?
What I tried so far
- BlueMail: support only for Exchange accounts, I contacted the developer. Perhaps it'll be implemented in the future)
- Samsung Mail: the new email counter on subfolders increases only after direct synchronization
- FairEmail: it synchronizes subfolders, but it's quite user-unfriendly
