Quoting Thomas Bruederli roundcube@gmail.com:
RoundCube sends an EXPUNGE command right after deleting a message in order to have it really deleted and not just marked as deleted. I think it's part of the IMAP server to update the message count after this.
Any ideas why this wouldn't be working for me if I attempt to delete more than 5 messages?
I'm running the version off of the CVS tree. The IMAP server appears to be Courier-IMAP.
Cheers, Matt
