=head1 SYNOPSIS
|
|
|
|
use Net::DNS;
|
|
$rr = Net::DNS::RR('name MINFO rmailbx emailbx');
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
Class for DNS Mailbox Information (MINFO) resource records.
|
|
|
|
=head1 METHODS
|
|
|
|
The available methods are those inherited from the base class augmented
|
|
by the type-specific methods defined in this package.
|
|
|
|
Use of undocumented package features or direct access to internal data
|
|
structures is discouraged and could result in program termination or
|
|
other unpredictable behaviour.
|
|
|
|
|
|
=head2 rmailbx
|
|
|
|
$rmailbx = $rr->rmailbx;
|
|
$rr->rmailbx( $rmailbx );
|
|
|
|
A domain name which specifies a mailbox which is
|
|
responsible for the mailing list or mailbox. If this
|
|
domain name names the root, the owner of the MINFO RR is
|
|
responsible for itself. Note that many existing mailing
|
|
lists use a mailbox X-request to identify the maintainer
|
|
of mailing list X, e.g., Msgroup-request for Msgroup.
|
|
This field provides a more general mechanism.
|
|
|
|
=head2 emailbx
|
|
|
|
$emailbx = $rr->emailbx;
|
|
$rr->emailbx( $emailbx );
|
|
|
|
A domain name which specifies a mailbox which is to
|
|
receive error messages related to the mailing list or
|
|
mailbox specified by the owner of the MINFO RR (similar
|
|
to the ERRORS-TO: field which has been proposed).
|
|
If this domain name names the root, errors should be
|
|
returned to the sender of the message.
