Ldap reject text MTA option

Direct LDAP attribute name MTA options:  (LDAP attribute name list)
The  MTA option specifies the names of group LDAP attributes, by default ,   , whose value will control what error text to use when  rejecting an attempted posting to a list due to the attempted posting failing an access check. Because the error text may appear in SMTP responses, it must conform to SMTP response limitations. In particular, it may consist merely of a single line of text limited to the US-ASCII charset. (If the value contains eight bit characters, the entire value will be ignored. If the value contains more than a single line of text, only the first line of text will be used.)
