NAME

Mail::Verp - encodes and decodes Variable Envelope Return Paths (VERP) addresses.

SYNOPSIS

  use Mail::Verp;
 
  #Using class methods
  #Change separator to something else
  Mail::Verp->separator('+');
  #Create a VERP envelope sender of an email to recipient@example.net.
  my $verp_email = Mail::Verp->encode('sender@example.com', 'recipient@example.net');
  #If a bounce comes back, decode $verp_email to figure out
  #the original recipient of the bounced mail.
  my ($sender, $recipient) = Mail::Verp->decode($verp_email);
 
 
  #Using instance methods
  my $verp = Mail::Verp->new(separator => '+');
  #Create a VERP envelope sender of an email to recipient@example.net.
  my $verp_email = $verp->encode('sender@example.com', 'recipient@example.net');
  #Decode a bounce
  my ($sender, $recipient) = $verp->decode($verp_email);

ABSTRACT

Mail::Verp encodes and decodes Variable Envelope Return Paths (VERP) email addresses.

DESCRIPTION

Mail::Verp encodes the address of an email recipient into the envelope sender address so that a bounce can be more easily handled even if the original recipient is forwarding their mail to another address and the remote Mail Transport Agents send back unhelpful bounce messages. The module can also be used to decode bounce recipient addresses.

FUNCTIONS

new()

Primarily useful to save typing. So instead of typing "Mail::Verp" you can say my $x = Mail::Verp->new; then use $x whereever "Mail::Verp" is usually required.

Accepts an optional "separator" argument for changing the separator, which defaults to hyphen '-'. The value can also be changed using the "separator" accessor.

my $x = Mail::Verp->new(separator => '+');

encode(LOCAL-ADDRESS, REMOTE-ADDRESS)

Encodes LOCAL-ADDRESS, REMOTE-ADDRESS into a verped address suitable for use as an envelope return address. It may also be useful to use the same address in Errors-To and Reply-To headers to compensate for broken Mail Transport Agents.

Uses current separator value.

decode(VERPED-ADDRESS)

Decodes VERPED-ADDRESS into its constituent parts. Returns LOCAL-ADDRESS and REMOTE-ADDRESS in list context, REMOTE-ADDRESS in scalar context. Returns VERPED-ADDRESS if the decoding fails.

Uses current separator value.

separator

Returns current value of the VERP "separator"

separator(SEPARATOR)

Sets new value for VERP "separator" and returns the previous value.
