Is that a message from the server? Is that the exact error message? I doubt it actually says 'Postbox'.

This does not sound like a message generated by Thunderbird. Have you logged into your account at your provider web mail page to see what your folders look like there? You might be surprised at what you find.

As for Thunderbird and deleting messages, pressing delete just hides the message and tags it for deletion. It is not permanently removed until you Compact the folder. Just because your inbox looks empty, if you have not compacted the folder they are all still taking up space.

Hi Christ, This is the message that is stated in the middle of the screen when I want to try to receive new email...

De map Postvak IN is vol en kan geen bijkomende berichten meer bevatten. Verwijder oude of ongewenste berichten en comprimeer de map om plaats te maken voor meer berichten.

In other words the Inbox is full and I cannot receive new email. Remove old or unwanted messages to make room for more messages.

with kind regards,

Fred

dear Airmail,

I have checked and removed nearly all email from my webmail. I have emptied the trashcan and I have 4gb of space allocated and have about 1.5 gb in use.

The message is placed everytime I try to receive new email: The message is:

De map Postvak IN is vol en kan geen bijkomende berichten meer bevatten. Verwijder oude of ongewenste berichten en comprimeer de map om plaats te maken voor meer berichten.

In other words the Inbox is full and I cannot receive new email. Remove old or unwanted messages to make room for more messages.

with warm regards,
