Hey 🙂

I updated to 20.0.1 without any error messages, all seems to work as usual, except mail-collector.

When I try collect an empty mailbox, no errors and the typical message “0 mails”.

When I try to collect a mailbox with mails in it, I get the following error:

```auto

```

Any ideas on this?
