Mozilla Thunderbird users: proper setup for IMAP on gigo.com
If you are going to use IMAP on gigo.com, and you’re going to use Mozilla, I recommend these options:
Tools -> Account Settings -> Server Settings -> “When I delete a message” is set to “Move it to the Trash folder”
Tools -> Account Settings -> Outgoing SMTP server -> [your server setting] – Set the port number to 587, and enable “TLS if possible”.
Tools -> Options -> Advanced -> General -> Config Editor
type “mail.imap.expunge_after_delete” and set the value to “true”.
(this will make sure the server actually deletes messages, not just marks them)
