How to send mail with the sendmail processes OFF in Solaris 10 -Beginner Question

[Database Administrator]

Our Solaris 10 (release 01/06) server is running sendmail v. 8.13.8.
We need to shut down SMTP and to kill the 2 sendmail processes below
but we also need to send mail from the server. Does anyone know
how to achieve this ?

Thanks, Bill


$ ps -ef | grep senamil

smmsp 1162 1 0 Oct 05 ? 0:04 /usr/lib/sendmail -

Okay, so you can't run any sendmail daemon? Or just not have one
listening on port 25? Is this a concern about bugs that sendmail fixed
over a decade ago, or to minimize any setup what-so-ever? I guess I
would advocate to still run the queue scanner sendmail daemon, and use
sendmail, but just not have it listen to port 25 externally.

Ie. sendmail to send outgoing email depends on one of those daemons
running, no matter if it is listening to port 25 or not. If you can't
have *that* daemon run, then you can't use sendmail for outgoing
email, which is the default installed MTA. Simple as that.

There are other solutions, but you will then need to add on software
to do the same thing as sendmail, or rewrite your apps depending on
what they need. There are simple outbound SMTP packages written for
various programming languages. You could change your code to use those
for outbound email.

Postfix probably wouldn't be a solution, because you need to run its
queue runner daemon as well. There are other MTAs, which may not need
a queue runner daemon, but they are pretty few.

So, what are the main concerns with having the sendmail daemons running?

Postfix is a great replacment for junk like sendmail.

stopping and uninstalling all sendmail packages is one of the first things
I do on a solaris machine.

This appears to be a contradiction in terms. You have to send mail?
AND you have to shut down sendmail?

Exactly what problem are you trying to solve here? Are you looking for
a replacement for sendmail?

You don't need to run any bits of sendmail (daemon or otherwise) to
send (space) mail, as long as your MTA's somewhere else.

Anyway, the OP needs to find the sendmail services and disable them.
Something like this, though I'm away from a Solaris box to verify:

svcs -a | grep smtp
svcadm disable

That is always worthwhile :-)

Let's not be too hard on sendmail. Sure it's a kludge. But look at the
time period it came from. I'm old enough to remember it. I can
remember "bang" style addressing (rgilbert!comcast!net or something like
that. It was as much a "return path" as it was an address. There were
not yet any real standards for mail or much of anything else.

Sendmail understood most of the "proto-protocols" and frequently managed
to get the mail delivered somehow or other. It still does.

I use my Windoze system and Thunderbird to send and receive mail so all
this is pretty much "academic" from my point of view.

You need to build a new sendmail.cf from the
/etc/mail/cf/cf/subsidiary.mc template which incorporates this line:

DAEMON_OPTIONS(`NAME=NoMTA4, Family=inet, Addr=127.0.0.1')dnl
DAEMON_OPTIONS(`NAME=NoMTA6, Family=inet6, Addr=::1')dnl <- IPv6 ONLY

Note: This line must be inserted AFTER the DOMAIN(`solaris-generic')dnl
line! Use of the "Family=inet6" line on systems without IPv6 running
will cause the sendmail function to fail.

"Managing Mail Delivery by Using an Alternate Configuration (Task)

To facilitate the transport of inbound mail and outbound mail, the new
default configuration of sendmail uses a daemon and a client queue
runner. If you have disabled your daemon, you should perform the
following task. For a detailed explanation, refer to New Configuration
File, submit.cf."
