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?

qmail-remote(8) System Manager's Manual qmail-remote(8)
NAME
qmail-remote - send mail via SMTP
SYNOPSIS
qmail-remote host sender recip [ recip ... ]
DESCRIPTION
qmail-remote reads a mail message from its input and sends the message to one or more recipients at a remote host.
The remote host is qmail-remote's first argument, host. qmail-remote sends the message to host, or to a mail exchanger for host listed in
the Domain Name System, via the Simple Mail Transfer Protocol (SMTP). host can be either a fully-qualified domain name:
silverton.berkeley.edu
or an IP address enclosed in brackets:
[128.32.183.163]
The envelope recipient addresses are listed as recip arguments to qmail-remote. The envelope sender address is listed as sender.
Note that qmail-remote does not take options and does not follow the getopt standard.
TRANSPARENCY
End-of-file in SMTP is encoded as dot CR LF. A dot at the beginning of a line is encoded as dot dot. It is impossible in SMTP to send a
message that does not end with a newline. qmail-remote converts the UNIX newline convention into the SMTP newline convention by inserting
CR before each LF.
It is a violation of the SMTP protocol to send a message that contains long lines or non-ASCII characters. However, qmail-remote will hap-
pily send such messages. It is the user's responsibility to avoid generating illegal messages.
RESULTS
qmail-remote prints some number of recipient reports, followed by a message report. Each report is terminated by a 0 byte. Each report
begins with a single letter:
r Recipient report: acceptance.
h Recipient report: permanent rejection.
s Recipient report: temporary rejection.
K Message report: success. host has taken responsibility for delivering the message to each acceptable recipient.
Z Message report: temporary failure.
D Message report: permanent failure.
After this letter comes a human-readable description of what happened.
The recipient reports will always be printed in the same order as qmail-remote's recip arguments. Note that in failure cases there may be
fewer recipient reports than recip arguments.
qmail-remote always exits zero.
CONTROL FILES
helohost
Current host name, for use solely in saying hello to the remote SMTP server. Default: me, if that is supplied; otherwise qmail-remote
refuses to run.
smtproutes
Artificial SMTP routes. Each route has the form domain:relay, without any extra spaces. If domain matches host, qmail-remote will
connect to relay, as if host had relay as its only MX. (It will also avoid doing any CNAME lookups on recip.) host may include a
colon and a port number to use instead of the normal SMTP port, 25:
inside.af.mil:firewall.af.mil:26
relay may be empty; this tells qmail-remote to look up MX records as usual. smtproutes may include wildcards:
.af.mil:
:heaven.af.mil
Here any address ending with .af.mil (but not af.mil itself) is routed by its MX records; any other address is artificially routed to
heaven.af.mil.
The qmail system does not protect you if you create an artificial mail loop between machines. However, you are always safe using smt-
proutes if you do not accept mail from the network.
timeoutconnect
Number of seconds qmail-remote will wait for the remote SMTP server to accept a connection. Default: 60. The kernel normally imposes
a 75-second upper limit.
timeoutremote
Number of seconds qmail-remote will wait for each response from the remote SMTP server. Default: 1200.
