Missing attachment when email is not multipart and only contains an attachment about postal HOT 7 OPEN

Oh and for some context at first we though the bug was #1624

from postal.

I presume you're sending this message with SMTP and not the API? And also that the message arrives at its destination okay with the attachment intact?

from postal.

Indeed the message is an incoming email into postal that should then trigger an HTTP endpoint that forwards the mails to our application. To the best of my knowledge, the message does not include the attachment in the HTTP endpoint json call.

(oh and happy new year by the way !)

Haha happy new year indeed!

Whatever sends the message with Amazon SES to Postal doesn't construct it with parts, Postal won't identify the attachment at all. Even the scanners I've seen use message parts, are you constructing this message yourself or do you have another device involved?

from postal.

I was indeed surprised to see the absence of parts in the email. The email is generated by a company that sends it to our company, we're looking into the possibility of ask them to change the way it is generated. But some mail clients seems to think the email is valid, I haven't found a tool that says the email is invalid.

Yeah its definitely Postal being very strict in this context but I'm not sure how extensive the changes would need to be in order to parse it.

I can't immediately see where the attachments are parsed out in either lib/postal/smtp_server/client.rb or lib/postal/message_db/database.rb or lib/postal/message_db/message.rb
