Can't limit number of emails stored on phone
1. I want Thunderbird to automatically erase all but the most recent 250 on my phone as it downloads new ones from my server. As it does so, I do not want the downloaded messages marked as "read" on my server, nor do I want messages erased on my phone to be deleted from my server. (That is all to be taken care of by my desktop email program.)
Phone: Moto g power 5G - 2024; OS: Android 15; Thunderbird v: 23.0 Settings: Fetching mail - Local folder size: 250 messages - Sync server deletions: Off - Mark as read when deleted: Off When I delete a message: Do not delete on server - Erase deleted messages on server: Manually
At present, Thunderbird downloads all the incoming messages and leaves them on, so I quickly find I have 1000+ messages stored on my phone. This eventually slows it's performance notably. I have to manually erase the messages, and then empty the trash, in order to circumvent this problem.
Also, when my desktop downloads the email, many of them are now marked read, even though I haven't read them. I am wondering if Thunderbird for Android isn't marking some or all emails as read on my server as it downloads them to my phone?
