Remove legitimate Fastmail domains from blocklist

[ChaosCrafter]

Hi — I'm from the Trust & Deliverability team at Fastmail (fastmail.com). We've found that some of our legitimate service domains are listed in this blocklist, which is causing reputation issues for our users.
The following domains are owned and operated by Fastmail and are used for real, permanent email accounts — not disposable or throwaway email:
fastmessaging.com
mailhaven.com
nospammail.net
reallyfast.info
veryfast.biz
Could you please remove these from the blocklist?

hi, thanks for your feedback. all domains show up as disposable or spam at https://check-mail.org/domain/reallyfast.info

those folks are quite responsive when it comes to invalid data: support@check-mail.org

once they are removed there, we will follow suite.
