V0.42b upgrade strangeness

no errors when upgrading from v.041 to v0.42b; however, now all my domains have odd subdomains added to them such as autoconfig.domainname.tld and autodiscover.domainname.tld. is this normal/to be expected? if yes what is this accomplishing?
thank you!

That’s not odd … Needed to provide autoconfig & autodiscover for email clients. Additional info. : https://github.com/mail-in-a-box/mailinabox/pull/1606#event-2472098282

Aaah…missed that. Thank you!
