Some global service providers may accept email from the postfix MTA in your server. Alternately, you can configure postfix to relay the message via a 'smart_host' (preferred method). It will require you to provide a valid email address + plus password for your postfix (client) to do authenticate itself and send the outgoing message. There is ample documentation on the 'Net to accomplish this. -- Arun Khan ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

One mailbox and 2 mta servers. on mailbox server where no mta is installed, I want to backup mailboxes with a script. I have set it up to /etc/cron.d/backup file. After the backup, I want to an email to be sent to admin account. for the moment, I get an OUTPUT in this way.

There is a tool named SendEmail, which is a perl script that performs the sending side (not receiving) of SMTP email handling.

If you decide a full blown MTA is too heavy weight in your environment on the different nodes (Postfix isn't the ideal choice for a so called null client), then have a look at ssmtp for example. It is provided by EPEL http://pkgs.org/centos-6-rhel-6/epel-x86_64/ssmtp-2.61-19.el6.x86_64.rpm.html It does exactly what you intend to do.

That compiles very easily on CentOS, however. Again, not sure if it can be used without making use of your ISP's mail server.

You are correct, a null client sends towards a central mailhub. That will be a properly configured MTA which does everything necessary to be compliant with current mail exchange standards. >> There is another null client called msmtp >> >> http://msmtp.sourceforge.net/ > >> but that one isn't available being packaged for CentOS. > > > That compiles very easily on CentOS, however.

Even if it is a small program which compiles easily. Unless you anyhow manage to maintain your own set of RPMs and your local yum repository. > I have an ancient page (slow site, not always up) on ssmtp, at > http://www.scottro.net/qnd/qnd-ssmtp.html.

Good point. I see an rpm for Fedora 17, but nothing earlier.

I usually do this:

The following script works for us to send notifications to a mobile "server"
that can not process very long text messages. Unless you have perfect control
over who is allowed to use this script and what is being sent, it is VERY bad
security practice. Replace the bracketed setup stuff (inside <> ) with the
appropriate sources and destinations. "$argv" passess the raw data to be
transmitted. Depending on what's in the message, you may have to modify
the 3rd through 6th lines.YMMV.

It CAN be a useful tool for those who don't want a large and complicated program lurking there all the time. i've no clue how other mail handlers are configured, never having done it, but it for sure beats sendmail all hollow if all you want to do is send an occasional mail and can't wrap your mind around its configuration.

This is how I have implemented a "retry" using the cleancode-email program that
I mentioned earlier today.
for(;;)
{
FILE *capturestderr;
system(temp);
capturestderr=openfile(STDERRCAPTURE,"r");
fseek(capturestderr,0L,SEEK_END);
if (ftell(capturestderr))
{
logtime(log);
fprintf(log,"%s -- %s ** SEND FAILED ** on
EMAIL MAILOUT, retrying\n",subscription.name,subscription.email); closefile
(capturestderr); sleep(2);
}
else
{
closefile(capturestderr);
break;
}
}
remove(STDERRCAPTURE);
