CentOS - Jul 2006 - nullmailer recommendations

Just wondering what people tend to use for nullmailers on their 
centos boxes (i.e. a minimal outgoing-only MTA)? I guess the obvious
solution is a minimal postfix config, but that seems reasonably
heavyweight and easy to misconfigure - is there anything lighter 
floating around the centos universe?

Cheers,
Gavin

The default install of sendmail listens on 127.0.0.1 only and should
serve your needs if I understand them correctly.

Gavin,

	How complex are your emails?? I need to do the same thing, and can't
get sendmail to email within my domain. I can send emails outside my
company, but not to an internal SMTP server. I'm working on a small perl
script that will do what I need - inject email into my internal SMTP server,
with attachments. I need simple email notification when cronjobs finish...
If you're interested, I can post this script to the list, hopefully later
today.

Well, I tried you suggestion to my previous email, and they didn't work.
Now, I'm sure it's because I'm not experienced in sendmail.

Me too! But I did some reading, looked at things,... and do have an
extensive *general* background. So there's probably some other piece of
the puzzle that's not right or is different.

There's lots of experienced folks here though. I bet if you posted in
the form of some background, a starting description of the pertinent
components in your setup, snippets of logs, etc. they would jump in and
help.

At least, that's been my observation. Fridays may be the exception
though.

I'll also try and help, within my limits.

Bill,

	Thanks for the offer of help! Time is short. It's going to take me
about an hour to write up a SMTP email injection script - barring any crazy
interruptions. Trying to tackle sendmail will take much longer, time I just
don't have right now. Once the script is done, I'll gladly post it to
the
list for others to use... I find it hard to believe though that no one else
has created a script like this. Using Krugle didn't turn up much...

I actually have exim running on everything around here.
Once you learn the ins and outs of configuring it, you can do anything
but the most complex configurations in about 2 or 3 minutes tops.

Well, it may just work for some, but not for others - I'm sure I'm not
alone
in sendmail not 'just working'. Using sendmail/postfix/qmail to send
simple
email from cronjobs is like using a jackhammer to drive finishing nails. Why
go through all that hassle of sendmail and it's near daily security problems
for such a simple task? My network has mixed CentOS and Gentoo systems, with
the Gentoo systems not having sendmail installed. Installing sendmail on
those systems would take far more time then coming up with a simple script
to do what I need. Take into account running another binary, it's just
another service taking up resources that doesn't have to be used.

I've always been a fan of msmtp:

   http://msmtp.sourceforge.net/

It's simple, easy and effective - installs with minimal fuss and 
provides a nice clean outgoing-only MTA. You can grab a SRPM from here:

   http://www.haleph.com/projects/fedora-rpms/

...and simply rpm --rebuild it on any CentOS box to get the flavor you 
need. I've really only used it on Fedora, but CentOS isn't that far
off...
