Editing sendmail to point to a different smtp server

English Network/Internet

Hi,

I have apache and php installed on a Suse linux machine and I need to make sendmail point to a different smtp server but I’m not sure how to. I tried looking for the file /etc/mail/sendmail.mc but couldn’t find there or anywhere on the filesystem. There’s a directory /etc/postfix and in there contain many files such as main.cf, master.cf, etc. Would those files be the file to edit to have sendmail point to a certain smtp server? Can someone give some input on how to do this?

Thanks

Hi
Postfix is the default now, so main.cf is the one. I suggest though you
use YaST MTA to configure as this should (in theory) respect your
changes if there are updates to postfix. Else you will need to keep a
backup to restore on a postfix update.

Hi Malcolm,

If I edit the main.cf, which variable should I edit? Should I restart postfix after that? Also if I use YaST MTA, how do I do that? I haven’t use YaST MTA before.

Thanks

Hi
I would have a read of this thread;
http://forums.opensuse.org/network-internet/393477-how-configure-mail-transfer-agent.html

However you should just be able to add the relayhost in main.cf. Here
is the comments in that section.


# INTERNET OR INTRANET

# The relayhost parameter specifies the default host to send mail to
# when no entry is matched in the optional transport(5) table. When
# no relayhost is given, mail is routed directly to the destination.
#
# On an intranet, specify the organizational domain name. If your
# internal DNS uses no MX records, specify the name of the intranet
# gateway host instead.
#
# In the case of SMTP, specify a domain, host, host:port, [host]:port,
# [address] or [address]:port; the form [host] turns off MX lookups.
#
# If you're connected via UUCP, see also the default_transport
parameter.

Would this work if i run as root:

postconf -e “relayhost = smtp.xxx.xxx”
postfix reload
