Hi,
I notice that my relay on sendmail.cf is just "DS" and no ip. So I guess, it's using the local DNS to relay my mail which sometimes being spammed. I would like to add a new relay ip "DSxxx.xxx.xxx.xxx" on sendmail.cf.
What do I need to edit sendmail.cf? Do I just use vi or m4?

TRIVIAL-REWRITE(8) System Manager's Manual TRIVIAL-REWRITE(8)
NAME
trivial-rewrite - Postfix address rewriting and resolving daemon
SYNOPSIS
trivial-rewrite [generic Postfix daemon options]
DESCRIPTION
The trivial-rewrite daemon processes two types of client service requests:
rewrite
Rewrite an address to standard form. The trivial-rewrite daemon by default appends local domain information to unqualified
addresses, swaps bang paths to domain form, and strips source routing information. This process is under control of several configu-
ration parameters (see below).
resolve
Resolve an address to a (transport, nexthop, recipient) triple. The meaning of the results is as follows:
transport
The delivery agent to use. This is the first field of an entry in the master.cf file.
nexthop
The host to send to. For local delivery this is an empty string.
recipient
The envelope recipient address that is passed on to nexthop.
The trivial-rewrite daemon by default only distinguishes between local and non-local mail. For finer control over mail routing, use
the optional transport(5) lookup table.
This program expects to be run from the master(8) process manager.
STANDARDS
None. The command does not interact with the outside world.
SECURITY
The trivial-rewrite daemon is not security sensitive. By default, this daemon does not talk to remote or local users. It can run at a
fixed low privilege in a chrooted environment.
DIAGNOSTICS
Problems and transactions are logged to syslogd(8).
BUGS
CONFIGURATION PARAMETERS
The following main.cf parameters are especially relevant to this program. See the Postfix main.cf file for syntax details and for default
values. Use the postfix reload command after a configuration change.
Miscellaneous
inet_interfaces
The network interfaces that this mail system receives mail on. This information is used to determine if user@[net.work.addr.ess] is
local or remote.
mydestination
List of domains that this machine considers local.
myorigin
The domain that locally-posted mail appears to come from.
resolve_unquoted_address
When resolving an address, do not quote the address localpart as per RFC 822, so that additional @, % or ! characters remain visi-
ble. This is technically incorrect, but allows us to stop relay attacks when forwarding mail to a Sendmail primary MX host.
Rewriting
allow_percent_hack
Rewrite user%domain to user@domain.
append_at_myorigin
Rewrite user to user@$myorigin.
append_dot_mydomain
Rewrite user@host to user@host.$mydomain.
swap_bangpath
Rewrite site!user to user@site.
Routing
local_transport
Where to deliver mail for destinations that match $mydestination or $inet_interfaces. The default transport is local.
Syntax is transport:nexthop; see transport(5) for details. The :nexthop part is optional.
default_transport
Where to deliver non-local mail when no information is explicitly given in the transport(5) table. The default transport is smtp.
Syntax is transport:nexthop; see transport(5) for details. The :nexthop part is optional.
parent_domain_matches_subdomains
List of Postfix features that use domain.tld patterns to match sub.domain.tld (as opposed to requiring .domain.tld patterns).
relayhost
The default host to send non-local mail to when no entry is matched in the transport(5) table.
When no relayhost is specified, mail is routed directly to the destination's mail exchanger.
transport_maps
List of tables with domain to (transport, nexthop) mappings.
