NAME

Mail::Internet - manipulate email messages

SYNOPSIS

use Mail::Internet;
my $msg = Mail::Internet->new(\*STDIN);

DESCRIPTION

This package implements reading, creating, manipulating, and writing email messages. Sometimes, the implementation tries to be too smart, but in the general case it works as expected.

If you start writing a new application, you should use the Mail::Box distribution, which has more features and handles messages much better according to the RFCs. See https://perl.overmeer.net/mailbox/. You may also chose MIME::Entity, to get at least some multipart support in your application.

METHODS

Constructors

$obj->dup()

Duplicate the message as a whole. Both header and body will be deep-copied: a new Mail::Internet object is returned.

$obj->extract(\@lines)

Extract header and body from an ARRAY of message lines. Requires an object already created with new(), which contents will get overwritten.

$obj->new( [$arg], [%options] )

Mail::Internet->new( [$arg], [%options] )

$arg is optional and may be either a file descriptor (reference to a GLOB) or a reference to an array. If given the new object will be initialized with headers and body either from the array of read from the file descriptor.

The Mail::Header::new() %options Modify, MailFrom and FoldLength may also be given.

-Option--Default
 Body    []
 Header  undef

Body => ARRAY-of-LINES: The value of this option should be a reference to an array which contains the lines for the body of the message. Each line should be terminated with \n (LF). If Body is given then Mail::Internet will not attempt to read the body from $arg (even if it is specified).
Header => Mail::Header: The value of this option should be a Mail::Header object. If given then Mail::Internet will not attempt to read a mail header from $arg, if it was specified.

$obj->read($fh)

Read a message from the $fh into an already existing message object. Better use new() with the $fh as first argument.

Accessors

$obj->body( [$body] )

Returns the body of the message. This is a reference to an array. Each entry in the array represents a single line in the message.

If $body is given, it can be a reference to an array or an array, then the body will be replaced. If a reference is passed, it is used directly and not copied, so any subsequent changes to the array will change the contents of the body.

$obj->head()

Returns the Mail::Header object which holds the headers for the current message

Processing the message as a whole

$obj->as_mbox_string( [$already_escaped] )

Returns the message as a string in mbox format. $already_escaped, if given and true, indicates that escape_from() has already been called on this object.

$obj->as_string()

Returns the message as a single string.

$obj->print( [$fh] )

Print the header, body or whole message to file descriptor $fh. $fd should be a reference to a GLOB. If $fh is not given the output will be sent to STDOUT.

example:

$mail->print( \*STDOUT );  # Print message to STDOUT

$obj->print_body( [$fh] )

Print only the body to the $fh (default STDOUT).

$obj->print_header( [$fh] )

Print only the header to the $fh (default STDOUT).

Processing the header

Most of these methods are simply wrappers around methods provided by Mail::Header.

$obj->add(PAIRS): The PAIRS are field-name and field-content. For each PAIR, Mail::Header::add() is called. All fields are added after existing fields. The last addition is returned.
$obj->combine( $tag, [$with] ): See Mail::Header::combine().
$obj->delete( $tag, [$tags] ): Delete all fields with the name $tag. Mail::Header::delete() is doing the work.
$obj->fold( [$length] ): See Mail::Header::fold().
$obj->fold_length( [$tag], [$length] ): See Mail::Header::fold_length().
$obj->get( $tag, [$tags] ): In LIST context, all fields with the name $tag are returned. In SCALAR context, only the first field which matches the earliest $tag is returned. Mail::Header::get() is called to collect the data.
$obj->header(\@lines): See Mail::Header::header().
$obj->replace(PAIRS): The PAIRS are field-name and field-content. For each PAIR, Mail::Header::replace() is called with index 0. If a $field is already in the header, it will be removed first. Do not specified the same field-name twice.

Processing the body

$obj->remove_sig( [$nlines] )

Attempts to remove a user's signature from the body of a message. It does this by looking for a line equal to '-- ' within the last $nlines of the message. If found then that line and all lines after it will be removed. If $nlines is not given a default value of 10 will be used. This would be of most use in auto-reply scripts.

$obj->sign(%options)

Add your signature to the body. remove_sig() will strip existing signatures first.

-Option   --Default
 File       undef
 Signature  []

File => FILEHANDLE: Take from the FILEHANDLE all lines starting from the first --.
Signature => STRING|ARRAY-of-LINES

$obj->tidy_body()

Removes all leading and trailing lines from the body that only contain white spaces.

High-level functionality

$obj->escape_from()

It can cause problems with some applications if a message contains a line starting with `From ', in particular when attempting to split a folder. This method inserts a leading `'> on any line that matches the regular expression /^*From/>

$obj->nntppost( [%options] )

Post an article via NNTP. Requires Net::NNTP to be installed.

-Option--Default
 Debug   <false>
 Host    <required>
 Port    119

Debug => BOOLEAN: Debug value to pass to Net::NNTP, see Net::NNTP
Host => HOSTNAME|Net::NNTP object: Name of NNTP server to connect to, or a Net::NNTP object to use.
Port => INTEGER: Port number to connect to on remote host

$obj->reply(%options)

Create a new object with header initialised for a reply to the current object. And the body will be a copy of the current message indented.

The .mailhdr file in your home directory (if exists) will be read first, to provide defaults.

-Option  --Default
 Exclude   []
 Indent    '>'
 Keep      []
 ReplyAll  false

Exclude => ARRAY-of-FIELDS: Remove the listed FIELDS from the produced message.
Indent => STRING: Use as indentation string. The string may contain %% to get a single %, %f to get the first from name, %F is the first character of %f, %l is the last name, %L its first character, %n the whole from string, and %I the first character of each of the names in the from string.
Keep => ARRAY-of-FIELDS: Copy the listed FIELDS from the original message.
ReplyAll => BOOLEAN: Automatically include all To and Cc addresses of the original mail, excluding those mentioned in the Bcc list.

$obj->send( [$type, [$args...]] )

Send a Mail::Internet message using Mail::Mailer. $type and $args are passed on to Mail::Mailer::new().

$obj->smtpsend( [%options] )

Send a Mail::Internet message using direct SMTP to the given ADDRESSES, each can be either a string or a reference to a list of email addresses. If none of To, <Cc> or Bcc are given then the addresses are extracted from the message being sent.

The return value will be a list of email addresses that the message was sent to. If the message was not sent the list will be empty.

Requires Net::SMTP and Net::Domain to be installed.

-Option  --Default
 Bcc       undef
 Cc        undef
 Debug     <false>
 Hello     localhost.localdomain
 Host      $ENV{SMTPHOSTS}
 MailFrom  Mail::Util::mailaddress()
 Port      25
 To        undef

Bcc => ADDRESSES

Cc => ADDRESSES

Debug => BOOLEAN

Debug value to pass to Net::SMTP, see <Net::SMTP>

Hello => STRING

Send a HELO (or EHLO) command to the server with the given name.

Host => HOSTNAME

Name of the SMTP server to connect to, or a Net::SMTP object to use

If Host is not given then the SMTP host is found by attempting connections first to hosts specified in $ENV{SMTPHOSTS}, a colon separated list, then mailhost and localhost.

MailFrom => ADDRESS

The e-mail address which is used as sender. By default, Mail::Util::mailaddress() provides the address of the sender.

Port => INTEGER

Port number to connect to on remote host

To => ADDRESSES

$obj->unescape_from(())

Remove the escaping added by escape_from().
