This class implements a regex-based RFC 2822 parser that locates email
addresses in strings and returns a list of C objects found.
Alternatively you may construct objects manually. The goal of this software is
to be correct, and very very fast.

Version 1.909 and earlier of this module had vulnerabilies
(L)
and (L)
which allowed specially constructed email to cause a denial of service. The
reported vulnerabilities and some other pathalogical cases (meaning they really
shouldn't occur in normal email) have been addressed in version 1.910 and newer.
If you're running version 1.909 or older, you should update!

Alternatively, you could switch to L|Email::Address::XS>
which has a backward compatible API. B

This method returns a list of C objects it finds in the input

multiple addresses.  The behavior in scalar context is undefined.

The specification for an email address allows for infinitely nestable comments.
That's nice in theory, but a little over done.  By default this module allows

C<$Email::Address::COMMENT_NEST_LEVEL> package variable to allow more.

  $Email::Address::COMMENT_NEST_LEVEL = 10; # I'm deep

The reason for this hardly-limiting limitation is simple: efficiency.

Long strings of whitespace can be problematic for this module to parse, a bug
which has not yet been adequately addressed.  The default behavior is now to
collapse multiple spaces into a single space, which avoids this problem.  To
prevent this behavior, set C<$Email::Address::COLLAPSE_SPACES> to zero.  This
variable will go away when the bug is resolved properly.

In accordance with RFC 822 and its descendants, this module demands that email
addresses be ASCII only.  Any non-ASCII content in the parsed addresses will

Modifying this package variable is now deprecated. Subclassing is now the
recommended approach.

=head2 Did I Mention Fast?

On his 1.8GHz Apple MacBook, rjbs gets these results:

  $ perl -Ilib bench/ea-vs-ma.pl bench/corpus.txt 5
                   Rate  Mail::Address Email::Address
  Mail::Address  2.59/s             --           -44%
  Email::Address 4.59/s            77%             --

  $ perl -Ilib bench/ea-vs-ma.pl bench/corpus.txt 25
                   Rate  Mail::Address Email::Address
  Mail::Address  2.58/s             --           -67%
  Email::Address 7.84/s           204%             --

  $ perl -Ilib bench/ea-vs-ma.pl bench/corpus.txt 50
                   Rate  Mail::Address Email::Address
  Mail::Address  2.57/s             --           -70%
  Email::Address 8.53/s           232%             --

...unfortunately, a known bug causes a loss of speed the string to parse has
certain known characteristics, and disabling cache will also degrade
performance.

=head1 PERL VERSION

This library should run on perls released even a long time ago.  It should work
on any version of perl released in the last five years.

Although it may work on older versions of perl, no guarantee is made that the
minimum required version will not be increased.  The version may be increased
for any reason, and there is no promise that patches will be accepted to lower
the minimum required perl.

=head1 ACKNOWLEDGEMENTS

Thanks to Kevin Riggle and Tatsuhiko Miyagawa for tests for annoying
phrase-quoting bugs!
