I have data in an email that should be seen as an attachment, but Thunderbird doesn't give me a way to access it or any indication that the data exists. iPhone exports its contacts as a multi-contact vcard (.vcf) file. This file was mailed to me, and I tried both a hotmail and a gmail address. The data is visible as an attachment at both sites. When the emails come to Thunderbird, there is no data visible as an attachment, or even as an image. There is nothing to indicate that there is data in the email. At first I thought that anti-virus software might have mistakenly removed it. However, looking at the message source, the data exists -- there is a base64 section that starts like this: Content-Type: text/x-vcard; name="MyContacts-2017-06-04-140219-178.vcf" Content-Description: MyContacts-2017-06-04-140219-178.vcf Content-Disposition: attachment; filename="MyContacts-2017-06-04-140219-178.vcf"; size=328289; creation-date="Sun, 04 Jun 2017 21:02:58 GMT"; modification-date="Sun, 04 Jun 2017 21:02:58 GMT" Content-ID: <44266F4ABA80F74DA9B312B5D5E6B076@namprd14.prod.outlook.com> Content-Transfer-Encoding: base64 It seems that Tbird is just not recognizing the attachment, so there is no "Save as..." or anything similar. Any ideas? I have had Apple-using people send me files in the past that I didn't get, and this makes me wonder if this could have been happening in other cases but I never thought to blame Tbird.
