SEARCH HEADER with quotes fails for iCloud

[Jivings]

It appears that any SEARCH HEADER command is failing against iCloud mailboxes due to the quote marks.

For example making the following query;

const query = [
  'ALL',
  ['SINCE', '9-Aug-2019']
  ['HEADER', 'FROM', 'james@squarecat.io']
];
client.search(query, (err, uuids) => {});

Debug tells me that this is the command performed;

UID SEARCH ALL SINCE 9-Aug-2019 HEADER "FROM" "james@squarecat.io"

Which results in a parse error.

If I do the same command using telnet then I get the same response;

However the same query without the quotes works great;

So it seems iCloud is falling over the quotes.

This works fine against all other servers I've tried, so perhaps iCloud specific.

Is there a way to get the command to run?

@Jivings I tried without HEADER so query would be only ['FROM' , "james@squarecat.io"] that worked for me

@mrgodhani that's because FROM is built in field you can search on. I need to search the headers, using the from header is just an example.

I also notice special characters won't work in search like if you do search for example 收据 it won't work and give bad parse error only for icloud since it tries to decode utf8.

@mrgodhani That wouldn't surprise me. Nothing to do with this though as these chars are all UTF-8.
