Sending mail from Linux--what's required?

OK, this is probably a very stupid question, and I feel a bit
embarrassed to ask. However, being reasonably new to Linux, I hope
that everyone won't look too unfavorably on me. : )

I am looking for a way to make Logwatch send reports to me nightly.
None of the Linux servers, except one running Postfix, actually send
their reports to the e-mail address specified in logwatch.conf. Do I
need to run a mail server, such as Postfix, on each and every Linux
server in order to get these logwatch reports e-mailed to me? If not,
what is needed on each Linux server in order to make it able to submit
e-mail messages via SMTP?

TIA for any help you can provide.

Yes.

Mail servers is what delivers the mail messages vi smtp.
So run postfix. If you want comment out the first line
smtp inet n - y - - smtpd

I can't say for all linux versions but normally only a local mail server
is installed by default. Meaning mali stays within the host machine. To
send mail to the real world or an inhouse network . YES you need a mail
server on each machine.

As these servers are production servers, I removed all non-essential
packages and left only those packages that were absolutely required for
each server's particular function. This is why none of them have
Sendmail (or Postfix, my MTA of choice) installed.

Looks like a full-blown MTA is needed, based on the responses seen thus
far. Thanks, I'll start researching an optimal Postfix configuration
for a server to act only as an SMTP client submitting messages to
another MTA. (Any suggestions out there?)

I don't think this is correct, you seem to be either misinterpreting or
misunderstanding the roles of MTAs and MUAs. There are many MUAs that
can be used to send mail to a central mail server.

OP: This article will show you how to use the sendmail software as an
MUA rather than an MTA. All you need is a mailserver somewhere on your
network. http://www.samag.com/documents/s=822...306a/0306a.htm

I hope this helps.

Kind Regards,

What about a nullmailer? Something like GNU mailutils mail.remote or
the like? All I need is something simple whose only purpose in life
would be to submit messages via SMTP to a separate mail server.

Nullmailer looks like it would do the job.
There are many, I believe there are perl scripts to do it as well.

Heck, I send send email just by using TELNET

telnet mailhost.mydomain.com:25
