No, suckless.org MX configuration hasn't changed since last April (2022). Also, you can test yourself to see that smtps and starttls are supported. (https://www.checktls.com/TestReceiver can help for example, if you don't trust your own setup) I suspect the problem is different, maybe rather a configuration change on your mail provider in february? In any case, that's not a refusal for help, don't hesitate to pass further information on if you find something new on either side!
