This function does NOT test the syntax of either the local part, or the host part, it will permit illegal characters on either side. 

Note that 'host' refers to the email domain, not actually to any host.

The at domain list is an obsolete addressing method which was available for routing email. RFC2822 says that it must be accepted, but should be ignored in routing.

Note that if an address doesn't contain a personal part, or an "at domain list", that part of the array will be missing.

Although RFC2822 permits consecutive comma separators in a list of email addresses, this function does not. That's probably a bug.

In the following list of examples, #4 uses an "at domain list",  #5 and after are illegal domains, but only the last actually generates an error.

$adds = 'ian eiloart <iane@example.ac.uk>, 
        shuf6@example.ac.uk, 
        blobby, 
        "ian,eiloart"<ian@example.ac.uk>,
        <@example.com:foo@example.ac.uk>,
        foo@#,
        ian@-example.com,
        ian@one@two';
$add_arr = imap_rfc822_parse_adrlist($adds, 'example.com');
var_export ($add_arr);

array (
  0 => 
  class stdClass {
    var $mailbox = 'iane';
    var $host = 'example.ac.uk';
    var $personal = 'ian eiloart';
  },
  1 => 
  class stdClass {
    var $mailbox = 'shuf6';
    var $host = 'example.ac.uk';
  },
  2 => 
  class stdClass {
    var $mailbox = 'blobby';
    var $host = 'example.ac.uk';
  },

  class stdClass {
    var $mailbox = 'ian';
    var $host = 'example.ac.uk';
    var $personal = 'ian,eiloart';
  },

  class stdClass {
    var $mailbox = 'foo';
    var $host = 'example.ac.uk';
    var $adl = '@example.com';
  },

  class stdClass {
    var $mailbox = 'foo';
    var $host = '#';
  },
  6 =>

    var $host = '-example.com';
  },

    var $host = 'one';
  },

    var $host = '.SYNTAX-ERROR.';

Invalid addresses, if detected, set host to '.SYNTAX-ERROR.'; but not all invalid addresses get detected as such, e.g. <.@host.do.main> is considered
valid though a single dot is not a valid local part without using quotation marks.
