       Okay... #sysadmins of #mastodon, I need your input. I'm running #Postscreen on my #postfix #email #server to greylist email from so far unknown sources.I'm receiving an account verification email from a mail server evidently belonging to mailgun.net. The issue is they never use the same IP twice. I'd have to allowlist all possible IPs somehow, but I'm somewhat at a loss how.Hostname of the email server stays the same, but IP address constantly changes.

       Can I somehow get all possible IP addresses to a particular hostname? I don't want to trust all IP addresses associated with mailgun.net just cause one particular service sends (verification) emails through them...
