Spec says:
${if <condition> {<string1>}{<string2>}}
If <condition> is true, <string1> is expanded and replaces the whole item;
otherwise <string2> is used. For example,
${if eq {$local_part}{postmaster} {yes}{no} }
The second string need not be present; if it is not and the condition is
not true, the item is replaced with nothing. Alternatively, the word 'fail'
may be present instead of the second string (without any curly brackets).
In this case, the expansion fails if the condition is not true. The
available conditions are described in section 9.4 below.
