The mail attribute is not multi-valued.

Why?

No.

Attributes are multi-valued by default. If you want them to be 
single-valued, you must specify it in the schema:

attributeTypes: (
   1.3.6.1.4.1.300.1.8.1
   NAME 'fooName'
   DESC 'Foo Name'
   SYNTAX 1.3.6.1.4.1.1466.115.121.1.26
   SINGLE-VALUE
   )

That depends on the usage. If you are setting up an MTA to do deliveries 
based on LDAP queries, then the MTA might use multiple attributes.

Qmail-LDAP reads "mail" first, and then "mailAlternateAddress" (which is 
multi-valued) second. So, with Qmail-LDAP, a user's main address is 
assigned to mail and all subsequent addresses are assigned to 
mailAlternateAddress.

See the following schema for examples:
