Mail::Address - Parse mail addresses SYNOPSIS
use Mail::Address; my @addrs = Mail::Address->parse($line); foreach $addr (@addrs) { print $addr->format," "; } DESCRIPTION
"Mail::Address" extracts and manipulates email addresses from a message header. It cannot be used to extract addresses from some random text. You can use this module to create RFC822 compliant fields. Although "Mail::Address" is a very popular subject for books, and is used in many applications, it does a very poor job on the more complex message fields. It does only handle simple address formats (which covers about 95% of what can be found). Problems are with o no support for address groups, even not with the semi-colon as separator between addresses; o limitted support for escapes in phrases and comments. There are cases where it can get wrong; and o you have to take care of most escaping when you create an address yourself: "Mail::Address" does not do that for you. Often requests are made to the maintainers of this code improve this situation, but this is not a good idea, where it will break zillions of existing applications. If you wish for a fully RFC2822 compliant implementation you may take a look at Mail::Message::Field::Full, part of MailBox. METHODS
Constructors Mail::Address->new(PHRASE, ADDRESS, [ COMMENT ]) Create a new "Mail::Address" object which represents an address with the elements given. In a message these 3 elements would be seen like: PHRASE <ADDRESS> (COMMENT) ADDRESS (COMMENT) example: Mail::Address->new("Perl5 Porters", ""); $obj->parse(LINE) Parse the given line a return a list of extracted "Mail::Address" objects. The line would normally be one taken from a To,Cc or Bcc line in a message example: my @addr = Mail::Address->parse($line); Accessors $obj->address() Return the address part of the object. $obj->comment() Return the comment part of the object $obj->format([ADDRESSes]) Return a string representing the address in a suitable form to be placed on a "To", "Cc", or "Bcc" line of a message. This method is called on the first ADDRESS to be used; other specified ADDRESSes will be appended, separated with commas. $obj->phrase() Return the phrase part of the object. Smart accessors $obj->host() Return the address excluding the user id and '@' $obj->name() Using the information contained within the object attempt to identify what the person or groups name is. Note: This function tries to be smart with the "phrase" of the email address, which is probably a very bad idea. Consider to use phrase() itself. $obj->user() Return the address excluding the '@' and the mail domain SEE ALSO
