Given that the *correct* PCRE expression for a valid email address is
3 pages long, the odds that yours is not rejecting some valid address
seem rather slim to me.
The . between the 9 and the - is not escaped, and renders the rest of
the characters in that class superfluous.
But let's suppose your PCRE actually proved the email syntactically
valid.
That's got *NOTHING* to do with the email generating a bounce or not!
There are a zillion times as many syntactically valid emails as there
are ones that don't bounce, never mind the even smaller class of email
addresses that actually go somewhere, and the even smaller class of
email addresses that a human reads on a regular basis.
