Guys (mozilla/email gurus),

For some reason, the .gif thumbnail and .pdf attachments names are not being handle properly in thunderbird. When a fax is received by hylafax/avantfax, a thumbnail of the fax is created in .gif format as 'thumb.gif' and a .pdf of the fax is created as 'fax.pdf'. Both of these are included as attachments to the mail notification sent by hylafax/avantfax. The php code that defines this is:

define('THUMBNAIL', 'thumb.gif'); <snip> define('PDFNAME', 'fax.pdf');

In the past, the fax notifications have come through with the proper attachments 'thumbs.gif' and 'fax.pdf'.

Now, in thunderbird, instead of getting 'thumbs.gif' and 'fax.pdf', you get attachments of 'Part 1.1.2' (instead of thumb.gif) and 'Part 1.2' (instead of fax.pdf).

I can save 'Part 1.1.2' as whatever.gif and save 'Part 1.2' as something.pdf and view them fine, but the problem is that something isn't working correctly in the attachment recognition in thunderbird. But what??

I have posted to the hylafax-user list and they have suggested it is an encoding issue in tbird. For grins, I have opened the emails in windows and they do come through as (ATT00007.gif and ATT00010.pdf) for example. That's fine, because the filetypes are correctly recognized.

Looking at the mail source in thunderbird (binary encoding snipped), I find:

Looking at the source above, I see that the content type looks correct as:

Content-Type: image/gif Content-Type: application/pdf

The mystery is why is thunderbird not listing these attachments as .gif and .pdf?

I have made the X-PHP-Originating-Script htmlMimeMail5.php available here just in case it is involved in this issue:

http://www.rlfpllc.com/dl/apps/avantfax/htmlMimeMail5.php.txt

There are some things I'm good at and others I'm not. Sorting out email attachment encoding issues definitely fall on the 'not' side :)

Wolfgang/All - does anybody have an idea what may be causing these .gif and .pdf attachments to be listed as 'Part 1.1.2' and 'Part 1.2' in thunderbird? More importantly - any idea how to make thunderbird list the attachments as something.gif and something.pdf as a fix?

Strange issue I know -- that's why I have to punt this one to the smart guys :p

Given that mime content, there is no mystery why the attachment has no filename, none was supplied. Content-Disposition: attachment needs to be Content-Disposition: attachment ; filename=thumb.gif ; The mystery is, whatever generated this email in the first place, why did it stop including a suggested filename for the attachment? -- bkw -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
