You are using ^ symbol which means that the string MUST START by:

 restricted|anonymous|private|unknown|unavailable

But your string $hdr("From") starts by "Unavailable" (*including* the
quotation marks so it doesn't match).

If the From URI username is enough (Restricted) you could do:

 pcre_match("$dU", "(?i)^(restricted|anonymous|private|unknown|
 unavailable)")

If you need to match the Display-Name ("Unavailable") then you must add the
quotation marks to the regular expression:

 pcre_match("$fn", "(?i)^(\")?(restricted|anonymous|private|unknown|
 unavailable)(\")?")

Note that I use $fn rather than $hdr("From"), being $fn the From Display-Name:
