[Workers] How to receive emails and get attachment

I see, thank you! Then if I'm understanding this correctly, my above method should actually be secure, right?

Would something like this be secure?

message.headers.get('from').endsWith('<[email protected]>')

message.headers.get('from').endsWith('<[email protected]>')

[Workers] How to receive emails and get attachment

I'm hoping that I can take a shortcut given the fact that I know for certain emails from my inbox will take the format of "Display name" <[email protected]>

I'm aware that it's very unlikely someone will figure that out, but I don't like the idea of security through obscurity

My only concern with that is, does the email protocol allow for someone to just insert angle brackets into their display name, therefore tricking the worker into thinking it's a legitimate address?

Or rather, not me changing it - it'd be my organisation changing it

I'd rather not hardcode the name part of it because then that means that the system would break if I changed my display name in my email client

Is it Good Enough™️ to just check for the part between the angle brackets or no?

Would message.from be the correct attribute for me to access in this case?

To summarise: - I want to only accept emails from a specific inbox - I control the sending inbox - I want this to be secure enough that no other inbox would be able to pass the filter

Or maybe I should have the worker forward all email, and instead have the safe validation be handled on my server side

So what would your advice be if I want a worker which only accepts emails from a specific inbox I control? Should I look for the parsing library you mentioned above?
