check_qmail_deliverable - Check that the recipient address is deliverable
See the description of Qmail::Deliverable.
This qpsmtpd plugin uses the client/server interface and needs a running qmail-deliverabled. If no connection can be made, deliverability is simply assumed.
The modules LWP (libwww-perl) and HTTP::Daemon, available from CPAN, are required for qmail-deliverabled and Qmail::Deliverable::Client.
Hostname (or IP address), and port (both!) of the qmail-deliverabled server. If none is specified, the default (127.0.0.1:8998) is used.
If the specification is prepended by the literal text smtproutes:,
then for recipient domains listed in your /var/qmail/control/smtproutes use their respective hosts for the check.
For other domains,
the given host is used.
The port has to be the same across all servers.
Example:
check_qmail_deliverable server smtproutes:127.0.0.1:8998
Use "smtproutes:8998" (no second colon) to simply skip the deliverability check for domains not listed in smtproutes.
Given a null host in smtproutes, the normal MX lookup should be used. This plugin does not do this, because we don't want to harrass arbitrary servers.
Connection failure is *faked* when there is no smtproute.
