Comment 2 for bug 1908557

Since it's unclear whether getmail is failing in the decision logic or whether server deletes are generally a problem, a test run was done with SimpleIMAPSSLRetriever and "delete = true". In this case, the error results:

'No mailbox exists with name "~/mail/yahoo_deleted.mbox"'

It's lying. "ls ~/mail/yahoo_deleted.mbox" reveals the file that was made with touch. So it looks like there are 3 bugs at this point:

1. "delete_after = 90" doesn't trigger detection of msgs with a "Date:" ~7 years past.
2. "delete_dup_msgids = true" is not inhibiting storage of msgs with duplicate IMAP-generated IDs.
3. "move_on_delete" fails with error falsely claiming the mailbox does not exist.
