Hi everyone,

I have what I hope is a rather simple question. I'm not very familiar
with this area of system administration, so hopefully someone here can
point me in the right direction. I just got myself a FreeBSD VPS to
host a few of my websites. I need the processes on the server (PHP,
for example) to be able to send e-mail via /usr/sbin/sendmail. The
thing is that I don't actually want to run a mail server. My vps is
severely limited on disk space, and any mail I get I'll forward to my
gmail account anyway. I can obviously configure sendmail or postfix to
do this for me, but this seems a bit excessive for what I'm trying to
do. The mail load will be very light, and I'd prefer to conserve disk
space. Is there a port, perhaps, that will simply forward all mail
transmitted to /usr/sbin/sendmail to the destination SMTP server? The
only other thing it has to be able to do is use the aliases file to
determine the real e-mail of root, for example.

Like I said, I'm not too familiar with setting up mail servers, so if
this makes no sense to you please suggest an alternative. Just to
recap, I don't need local mail storage and I don't need the server to
accept mail from anything other than the local processes running on
the server. Just need it to read the destination e-mail address (or
get it via aliases), connect to the MX server for that domain, and
transmit the message. If there isn't any simple daemon that will do
this, can you recommend either how to configure sendmail or something
like postfix to do this? The idea is to minimize resource usage (disk
space, memory, cpu time).

Sounds to me you just have to enter the proper aliases (in
/etc/mail/aliases), run "newaliases", and you're done, i.e. point
everything to your own e-mail address?


Well I need sendmail running for that correct? Right now I've got it
disabled with sendmail_enable="NONE" in my rc.conf. I was hoping to
use something a bit less resource intensive, and with a better
security history. I am not really at all familiar with sendmail. I
tried figuring out how to configure and tune it properly in the past,
and realized that I have neither the time or patience for that task. I
know that it will probably work the way it comes by default with
FreeBSD, but I really don't like running daemons that I don't
understand or don't know how to configure and monitor.

If this is the most efficient solution to my problem, then I guess
I'll head over to the handbook and try to figure sendmail out. If you
have other suggestions, by all means, let me know. Otherwise, are
there at least parts of sendmail that I can disable?

There is nothing wrong with using sendmail.
If you want to 'receive' email at the address and forward it to
some other address, then there is nothing you have to do to configure it.
Just leave it at its defaults. Then put the aliases in as indicated.

If you want to be able to send out Email - say from processes, but
receive no email, not even to forward, then set it to 'no' in rc.conf.
