Please disable automatic EXPUNGE on IMAP download
Your IMAP server's automatic EXPUNGE feature confuses fetchmail, a program used to download e-mails under Linux.
More information can be found on this issue report on GitLab: https://gitlab.com/fetchmail/fetchmail/-/work_items/91
Please disable automatic EXPUNGE's, because they let fetchmail just die after downloading one message. If 10 messages are waiting, then fetchmail has to be re-run 10 times.
