Problems with Strato

[Olaf J.]

Hello,

I am sorry for my bad english.

I use K9 since a few years with IMAP Postboxes hosted by Ionos without any problems.

A few Days ago I transfered the postboxes to Strato. All Mails I copied with Outlook 2016 from Ionos into the new postboxes at Strato.

Now there is a problem using K9 IMAP access to the postboxes hosted by Strato.

When I configure K9 to sync 200 Mails it shows me the new Mails which where delivered new into the Strato postbox. This are less than 200.

Date 25.01. until 20.01.

Then K9 additionally shows the oldest Mails (year 2011) which I copied into the postbox at 20.01.

But I want K9 to show me the 200 newest Mails from today on.

With my other postbox at GMX everything is ok with the same settings.

Can anyone give me some help?

regards

Olaf
