Log 8bit encode MTA option

Transaction logging MTA options:  0 or 1)
The  MTA option controls how non-ASCII material is written to XML format MTA transaction log files. A value of 0 causes such material to be written as-is. Any nonzero value will cause all valid UTF-8 characters to be written as XML numeric character references.

How non-ASCII octets that does not begin a valid UTF-8 sequence is controlled by specific values of the  MTA option. Currently defined values are:



 Write the octet as a XML numeric character reference. Note that this is tantamount to interpreting the octet as a character in the ISO-8859-1 charset. 

 Write the octet as an XML entity reference of the form, where   is the lower-case hexadecimal representation of the octet. 

 Write out a space in place of the octet. 



Note that this setting only applies to XML format logs ( = 4); non-ASCII characters are always written as-is when other formats are used.
