If the customer domain does not exist (anymore), haproxy will refuse to reload. In this case the customer domain has to be removed and the customer to be notified.

27
* Configured by cdist, type @__ungleich_smtp_proxy@.
28
* To add an entry, edit @manifest/ungleich@.

** Find configuration entry for @ipv6-mx.ungleich.ch@.

** Add @--proxy domain.tld@ entry to the @__ungleich_smtp_proxy@ type. Make sure that @ipv6-mx.ungleich.ch@ is not the primary MX of @domain.tld@:t we will have routing loops if it is the case.
