I do not know where to report bugs, so I write here. I have some mailboxes. There were mails with attachments in them (not neccesarily tnef, also images). These mails vere put via mailpost to innd. And presented as usenet posts. And this is a problem. On mailbox addition works perfectly, but when I selected usenet newsgroup - thunderbird waits forever.
This review is for a previous version of the add-on (1.2.19).
