no From: header in mail - > empty from field

Would you please provide this mail as an attachment?

Changing this into a bug report as an empty From: field should definitly not lead to an empty "Sender" column in the listview.

Also changing status to pending to signal the user that he should reply within 14 days as otherwise this ticket will be automatically closed.

Trying to reply to #2 produce an error (but the comment was posted anyway):
Trac detected an internal error:
AttributeError: 'int' object has no attribute 'id'

I had an eye on the registration form, but FireFox complain that the certificate is not secure (and ask me if I want to make an exception. Can I really accept to trust a certificate that is not authenticated, even if a priori I trust the one that comes from yam.ch ?)

Yes of course you can as we simply don't have the money for a public SSL certificate that would please your browser per default. But it is safe to accept that as the current SSL certification is from my own server. So don't worry.

Done.
But now, when I'm logged in, I have the following error:
Trac detected an internal error:
SMTPRecipientsRefused: {u'AmigaPhil@…': (553, '5.3.0 <AmigaPhil@yam.ch>... No such user here')}

Ok, it works now.

Mail with no From:

Ok, it works now.

Ok, then please try to attach the mail here to this report.

Here it is.
(I was not sure if text attachment would be shown on the web, exposing the email addresses, so I packed the mobox file with lha.)

Ok, I verified the problem. And indeed, in case a mail does not have any From: header the corresponding list column also doesn't show anything. In that case something like "(no sender)" should be shown instead. Also the following questions have to be answered:

1. Is there another header entry (e.g. Sender usable for that?
2. What does the RFC says about something like that, is "Sender:" really the way to go?
3. How does e.g. Thunderbird treat that situation?

In addition the preselection window also doesn't show any sender address so if a fix is done it should address the problem in the preselection window as well.

But as this problem occurrs very rarely I'll set the priority of the ticket to low.

Replying to damato:

1. Is there another header entry (e.g. Sender usable for that?

From: Sender: and Reply-To: are the originator fields defined in RFC2822.

• From is required and must appear once in a mail header.
• Sender is optional, but required when From has multiple addresses
• Reply-To is optional

2. What does the RFC says about something like that, is "Sender:" really the way to go?

AFAIK, there is no RFC about how to resolve a missing From in a badly formatted message.

3. How does e.g. Thunderbird treat that situation?

Don't know about Thunderbird, but Thor falls back to Sender (maybe also Reply-To) when From is missing.

(In [4674]) * YAM_MAf.c: in case a mail contains no From: header line YAM now tries to

construct a valid sender from a possible Sender: header line. This might not
be perfect, but it is better than no name at all. This closes #117.
