# email_autodiscover - Dynamisches Autodiscover/Autoconfig Snippet
# Importiert im Caddyfile via: import email_autodiscover
#
# Funktioniert mit JEDER Domain automatisch, solange der Caddy-Block
# auf autodiscover.<domain> oder autoconfig.<domain> hört.
#
# Hostnames werden dynamisch abgeleitet:
#   autodiscover.cielectrical.com → imap.cielectrical.com / smtp.cielectrical.com
#   autoconfig.bayarea-cc.com     → imap.bayarea-cc.com / smtp.bayarea-cc.com
#
# {labels.2}.{labels.1} extrahiert die Basisdomain aus dem Host:
#   autodiscover.cielectrical.com → labels: [com=0, cielectrical=1, autodiscover=2]
#   → {labels.1}.{labels.0} = cielectrical.com
