# mailadminDns.sh
|
||||
# ------------------------------------------------------------------
|
||||
# Setzt AUSSCHLIESSLICH den DNS-Record fuer den mailadmin-Zugang.
|
||||
# Faesst NICHTS anderes an (kein SES, SPF, DKIM, MX, keine anderen
|
||||
# Subdomains). Kann gefahrlos auf bereits migrierten Domains laufen.
|
||||
#
|
||||
# Verwendet dieselbe ensure_record-Logik wie cloudflareMigrationDns.sh,
|
||||
# damit das Verhalten (Create/Update/Skip-bei-identisch) identisch ist.
|
||||
#
|
||||
# ------------------------------------------------------------------
|
||||
# PFLICHT-VARIABLEN:
|
||||
# DOMAIN_NAME Kundendomain, z.B. innungsapp.com
|
||||
# CF_API_TOKEN Cloudflare API Token
|
||||
#
|
||||
# OPTIONALE VARIABLEN:
|
||||
# MAILADMIN_HOST Subdomain-Label, Default: "mailadmin"
|
||||
# -> ergibt mailadmin.<DOMAIN_NAME>
|
||||
# MAILADMIN_TARGET CNAME-Ziel, Default: "mail.<DOMAIN_NAME>"
|
||||
# Beispiele:
|
||||
# mail.innungsapp.com (pro-Domain Modell)
|
||||
# mailadmin.bayarea-cc.com (zentrales Modell)
|
||||
# DRY_RUN "true" -> zeigt nur an, aendert nichts
|
||||
#
|
||||
# ------------------------------------------------------------------
|
||||
# BEISPIELE:
|
||||
#

# # Standard: mailadmin.innungsapp.com -> mail.innungsapp.com
|
||||
# DOMAIN_NAME=innungsapp.com CF_API_TOKEN=xxx ./mailadminDns.sh
|
||||
#
|

# # Zentrales Modell: mailadmin.innungsapp.com -> mailadmin.bayarea-cc.com
|

# DOMAIN_NAME=innungsapp.com \
