Can not send email using list (group)
Every time we try sending an email using a list (group) we get the following error - book group <members> is not a valid e-mail address because it is not of the form user@host. You must correct it before sending the e-mail.

Try rebuilding your Mailing List. I suspect the address book data file is corrupted.
Create a new empty List. Drag and drop the contents of the current one onto the new one's icon.
Tip: Thunderbird seems to be a bit picky about names for Mailing Lists. Avoid spaces and non-alphanumeric characters in their names.
