Please attach the original messasge to the bug report

It has been attached already (see spam.eml).

Ah yes. It's missing all the headers. That's odd. You are correct that the message does not show in the message list. Equally odd is I don't find any similar bug reports (open,dup,invalid,wontfix) which seems highly improbable. My search foo is off. rsx11m, aceman does it sound familiar

It is a feature that we do not show such malformed junk :) But I can't reproduce this. I put the eml file into a new folder (manual file manupulation), then started TB. The folder has one message (in the Total column) and it also has a row for the message in the message list. The From is shown as '-', Correspondents is '-', it does have a Date (probably from the "From - " message starter in the mbox file. Also it can be viewed and the only information shown is the "Z." body.

Hi all, got the same issue.

I have to login via a webmail (generally anything that can display the message) a delete it manually. I believe the problem lies in parsing the mail - it fails for some reason. Cheers! Jan

Gene fixed this in bug 1345266. That should be fixed in TB 52.7.
