[SOLVED] IMAP Error: Could not save message in Inbox.Drafts

[snowweb]

When I attempt to save a message as a draft or when Roundcube attempts to autosave it, I'm getting the error below and the message is not saved.

All other aspects of the mail service appear to be working. I can send and receive mail etc.

At first I thought this was a permissions error. These are the permissions on the Drafts folder in question. But I've relaxed the permissions as you can see below, with no effect.

I'm able to save into Inbox.Drafts remotely using IMAP from my local mailclient.

I'm using Dovecot and Postfix.

Where you see 'mydomain' this is a replacement I used instead of my domain name in the forum only. The actual files have my actual domain name in place of that.

Perhaps someone can see what I'm doing wrong?

Many thanks.

Well spotted, thanks Alec!

That solved it.
