Thunderbird quit receiving messages June 25th and quit copying messages to the sent folder at the same time. Are they connected somehow? I have checked my settings and they are all the same as they were before this happened and are correct. When I click on "Get Messages" these five quick messages appear in rapid succession: Looking for imap.pldi.net Looked for imap.pldi.net Connecting to imap.pldi.net Connected to imap.pldi.net Checking email server capabilities then goes away and no messages received. Regarding copying messages to drafts I get this with each message I send. "Your message was sent but a copy was not placed in your Sent Folder due to network or file access errors. You can retry or save the message locally to Local Folders/Sent (my email address)" with buttons "Retry" "Save" "Don't Save." The message remains on the screen until I click "Save" and the message goes away. I believe all of this happened with the last Thunderbird update, but I'm not real sure.
