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