error when sending a mail: KMAN

[jopo2]

Suddenly happened today that when I send an email via aquamail, I get a red error message "BAD kman<number> NO"
with <number> = 45, 54 or whatever..

Checking mails says NO mails.. But definitely there are!

What's wrong? How can I solve this problem?

Hi jopo,

Please send a screenshot of the exact error message you see.

Here is the screen shot for the SENT mails

As you can see, till ~07:00 everything works fine.
The problem has gone at about 08:43

All the sent mails DID in fact reach the recipient.
mails sent to my own account have been delivered as well, but when I checked my mails, I did only receive them AFTER 08:43

I would like to understand the reason for these KMAN errors.
Was this a problem of my mail hoster? (I called them and they said no problem at all).
So very strange situation.

Hi jopo,

Thanks for the screenshot. This can happen if the name of the folder on the server gets changed by your mail provider. Aqua Mail should just need to update the folder names.

You can follow the steps listed in this forum thread for a potential resolution.
