Loss of data in "From" header value, when value has a comma.

[glr0221]

In the file "dist/utils.js" you have the function encodeHeaderValue(). In that function when the key is "From", the code invokes convertAddresses(parseAddresses(value)); When this happens, the value "xxx, yyy [email protected]" becomes "yyy [email protected]".

Is the special handling of the comma-character because of the assumption that multiple email addresses are separated by commas? I don't think there can be multiple "From" addresses in an email though. If there can be only one "From" address, then the value should be used as is. Or am i mistaken that the "From" value can only be singular?

Thank you!!
