I am manually creating a multi-part MIME-formatted file and submitting it to an SMTP pickup directory. When the email arrives in my inbox it has lost the opening double-quote of any double-quote terms. e.g.

<html lang="eng">

becomes

<html lang=ng">

I have checked the file before i开发者_开发知识库t is submitted to SMTP (PowerMTA) and it does contain all the correct double-quotes etc.

What's happening here, and how do I code around it? My end-users will be using this solution to create HTML-based outbound email, so it needs to cope with any HTML content.

It's not about ", it's about = You should convert all your = to =3D. There are also other limitations that you can find in wikipedia.
