68.12.0 (64-bit) on Linux Manjaro. It connects server mail account via POP3, when i today clicked to get messages it downloaded 4, but in the Inbox on server is 13 (!!) and in Trash on server there is 199 emails (after a while i realised that these are from the time i was using IMAP possibly). And POP3 is able to download only from Inbox? Then i disabled all 3 filters i have for that account. Later, i have found that the remaining server Inbox mails was placed into client Trash folder. Even later when i have enabled filters, again e-mail are not downloaded. The status bar shows Downloading 1 out of 28 messages for a second, but then downloads 0 messages. Why? I see that this mail account settings was autodetected as non SSL: (port 110, security: STARTTLS). In Outgoing/SMTP server settings it used weird port 587 that i do not see mentioned on server + STARTTLS. Though SSL settings not helped with mentioned issue. Regarding issue with mails downloaded to local Trash, what helped was to go to Tools/Message Filters/Filter log (enable). Then after processing some mail, i have seen which filter caused the trashing and indeed i had wrong option in that filter (Match any/Match all conditions). I am not sure though regarding why it not downloaded from Inbox before and if really Trashed items could be from IMAP times and if POP3 unable to download from Trash.
