Ldap domain attr prefix text MTA option

Direct LDAP attribute name MTA options:  (LDAP attribute name(s))
The  MTA option specifies the name of a domain LDAP attribute which in turn is used to specify text to insert at the top of messages. The default LDAP attribute used for this purpose if this option is not specified is.

Any text specified by the attribute will be inserted into messages submitted by any authenticated user associated with the domain. Either plain text or HTML can be used. A maximum of 4096 octets from the attribute value will be processed.

HTML values are indicated in a prefix addition by enclosing the addition in &#x3c;html&#x3e;&#x3c;/html&#x3e; tags. (These tags are removed from the addition.)

Prefix additions to text/html parts are placed immediately after the &#x3c;body&#x3e; tag.

Plain text additions to text/html are preceded by &#x3c;br&#x3e;&#x3c;pre&#x3e; and followed by &#x3c;/pre&#x3e;&#x3c;br&#x3e;. HTML additions to text/plain parts have all HTML tags removed and all entities are converted to corresponding characters. Character set conversions are performed as needed; the attribute value must be specified in UTF-8.
