Specify the ``Channel Name''.
The name must begin with a letter and must contain
only letters and digits.
Select the ``Program''.
The channel program is used to invoke
this channel; it receives mail from
deliver(ADM)
and carries it to its destination on the local machine
or across the network to a remote machine.
The program must be installed in /usr/mmdf/chans.
Enter a ``Description'' of the channel.
This description is used by certain programs as a
display line to explain the function of the channel.
For example, the
checkque(ADM)
program uses this description in its status reports.
Select the name of the ``Table'' to be associated with
this channel. The table lists the hosts that are
accessible on this channel.
If you specify a new channel table name,
the name must begin with a letter and must contain
only letters and digits.
The new table will be defined
using the same ``Name'' and ``Description''
as are used to describe this channel.
For additional information, see
``Channel tables''.
Enter a ``Configuration string''.
This string specifies channel-specific configuration parameters.
For example, use this string to specify to a uucp channel
the number of addresses remote hosts can handle in a single message.
See
``Channel configuration strings''.
To specify channel address parameters, when
adding a channel
using the Channel Administration Manager,
select Add from the Channel menu, then
select Addressing:
Select the
Outgoing Address format.
This parameter specifies how the addresses in outgoing
message headers are reformatted on this channel:
RFC 822 uses RFC 822-style addresses (for example <@A:B@C>)
RFC 733 uses RFC 733-style addresses (for example B%C@A)
None message headers not reformatted
Specify the Addressing Options:
Select ``Domain Hiding'' if the machine cannot handle
domains delivered via this channel.
The leftmost part of domain names will be used.
Select ``Ignore nameserver timeouts''
if the host information for this channel is obtained from
a nameserver, and you want timeouts ignored.
If you do not select ``Ignore timeouts'',
MMDF uses the delay channel
to queue messages that temporarily fail address
verification because of unavailability of a name server.
When timeouts are ignored, MMDF searches other tables
for host information.
Select a table of known hosts
if you have selected ``Domain Hiding'' and
want to provide host information in a table.
This table must contain your local host's fully qualified host name.
If you specify a new table name,
the name must begin with a letter and must contain
only letters and digits.
For additional information, see
``Channel tables''.
To specify channel delivery options, when
adding a channel
using the Channel Administration Manager,
select Add from the Channel menu, then
select Delivery and make your selections:
Select a ``Delivery Mode'':
Regular
Mail is queued but not sent until deliver runs
(can be run manually, via
cron(C),
or as a background daemon).
Background only
The channel can be invoked only by a background deliver daemon.
Passive
The channel is used as a pickup channel only.
Immediate
The channel can be invoked immediately without having to batch messages.
Select one or more ``Delivery Options'':
Allow pick up
The channel can pick up mail from the remote host.
Allow sending
The channel can send mail to the remote host.
Sort by host
After the deliver program sorts by channel, it will also sort by host.
This allows as many messages as possible to be sent to a
host before the connection is broken.
Specify the ``Time-To-Live'' for undeliverable messages.
When there is a connection failure to a host, this value specifies
the number of minutes between connection retries. The default
value is 2 hours.
When you finish entering the delivery options, click on Close.
