+# WORKAROUNDS
+* Older systems that provide the older RFC-2553 implementation of getaddrinfo,
+  rather than the current RFC-3493, and systems that do not provide this
+  getaddrinfo() interface at all and thus use the replacement functions from
+  libesmtp/getaddrinfo.?, might return EAI_NODATA when a host is registered in
+  DNS as MX or similar, but without A or AAAA records.  Handle this situation
+  when checking for multidrop aliases and treat EAI_NODATA the same as
+  EAI_NONAME, i. e. name cannot be resolved.
+
+  The proper fix, however, is to upgrade the operating system.
