+# Documents refer to "internet 7" as "mail". This however leads to ambiguities
+# with RFC2798, Section 9.1.3, where "mail" is defined as the short name for
+# rfc822Mailbox. The short name is therefore here left out for a reason.
+# Subclasses of "mail", e.g. "MIME MHS" don't consitute a problem, as
+# references are realized via long name "Mail" (with capital M).
