Anyone else seeing failure of FM client to detect an .MHTML attachment from Gmail?
Gmail shows the message fine https://i.imgur.com/9C7jnSR.png
But Fastmail pretends there is no attachment https://i.imgur.com/cA5rATu.png . In Chrome and Firefox. Anyone else see this? This is a rather serious misrep of the message content by Fastmail. |
MHT and MHTML transfer as email attachment is not reliable
".mht" and ".mhtml" attachments are treated in different ways by various email systems.

Thanks for that info.

Still I'd be interested to hear if anyone else gets this. Quote:

My point is that Outlook.com to Fastmail works fine. It’s the Gmail outbound that seems to create an odd message format which can’t be read by Fastmail or Outlook.com. I sent a message from Gmail with To addresses at Fastmail and Outlook.com (one message with two recipients) and they were both received in a way which I think indicates that they were not properly parsed. Each receiving system interpreted the Gmail MHT attachment differently and neither was correct.
The problem is the Content-Type in the MIME block encapsulation and the MIME formatting. Look for the Content-Type header down at the start of the MIME block, not in the main contiguous header list before the first blank line. Both Fastmail and a Outlook.com can’t parse what Gmail is sending, leading to what both you and I reported. I found this old complaint; https://support.google.com/mail/foru...Gm4nj4M/?hl=en I created my MHT and MHTM files using both of these methods and they both work as I described:
