Internet addresses routinely contain the double quote character, ". In order to represent this character yet satisfy the quoting conventions of VMS MAIL, certain character substitutions must be made, as shown in Table 1-1 . These translations are necessary in order to allow specifying double quotes inside an address even though they are not normally allowed inside a VMS MAIL address. Preferred usage when entering addresses manually is to substitute single quotes for double quotes and \' for single quotes. For example:

IN%"'tony li'@hmc.edu"   maps to  "tony li"@hmc.edu 
IN%"\'tonyli\'@hmc.edu"  maps to  'tonyli'@hmc.edu 

Table 1-1 Foreign protocol address mapping

Sequence	Is translated to
'	"	(double quote)
\'	'	(single quote)
\d	"	(double quote)
\s	'	(single quote)
\D	"	(double quote)
\S	'	(single quote)
\\	\	(backslash)

Alternatively, you may find it convenient to use PMDF MAIL---which requires no special quoting or character substitutions when entering Internet addresses--- when sending to Internet addresses containing special characters.
