"""
+The flagship email-domain enabler and repair tool for Mailcow/PowerDNS infrastructures.
+
+The following checks will be performed:
+ DNS:
+ - DMARC record
+ - DKIM record
+ - MX1 + MX2 records
+ Mail:
+ - MX1 domain entry
+ - MX2 domain entry
+ - MX1 DKIM keypair
+
+If any of the checks fail, the failed operation will be written to the respective system, in addition to overwriting possibly existing DNS records with fresh DMARC/DKIM/SPF/MX records.
