Add support for Sieve filters in Stalwart via JMAP

[marclaporte]

Work was done to improve support between Stalwart JMAP and Cypht. General progress was made at #909 but Stalwart-Sieve-JMAP was not working so this is being spun off to a distinct task.

This is not a blocker to release Cypht 2.0

https://github.com/cypht-org/cypht/releases/tag/v2.0.0 has been released. Let's try to address in Cypht 2.1.0

@Shadow243 @Yannick243 Please describe what issues you were running into.

We're encountering issues with connecting to the Sieve protocol using Stalwart. While we've been successful in connecting to SMTP, IMAP, and JMAP, Sieve connection attempts result in a loop without any error messages

Ok, how about Sieve filters with other mail servers such as Cyrus?

For the record: We (well @Shadow243 mostly) will set up a dev/test server dedicated to testing the interoperability between Stalwart and Cypht. Server access will be provided to developers of the two communities. It will super useful to solve issues such as the current one.

I restarted all the configs from scratch and we now have at least an error message. We will start to debug from there.

'''
array(2) {
["code"]=>
string(2) "NO"
["data"]=>
string(31) ""Invalid AUTH=PLAIN challenge.""
}
'''

we are beginning to see light in the tunnel 😀

We are now able to connect to sieve, we can now start tests.
