SMTP

Hey all,
Does anyone one know of a good SMTP Server program. I want it to work on
a stand alone computer. I want to be able to use the program instead of my
ISP SMTP.

Thanks for any advice,

I will tell you that unless you have a static IP and a domain name with
reverse DNS lookup that matches, it won't work very well. What I do at home
is have a machine that among other things runs Mercury mail server (free
download). I use the SMTP Relay module, which takes all the email I send
and uses my ISP's SMTP server to resend it through. When their server dies
(often), mine just holds it and sends it later. Also lets you do stuff
like email pooling (downloads mail from a bunch of email accounts to a
local pop3 or IMAP account). Really nifty stuff.

Do NOT listen to the above "advice". It will lead you astray.

Download ArGoSoft freeware mail server from here:

Set your email program SMTP address to 127.0.0.1 and everything will work fine.

Ok, here's the deal Ava. I use a real mail server at home. If you are
just sending it from your IP address, there are a good percentage of mail
servers that will reject your mail. Why? You are not someone on their
network (based on having a different IP range), and your computer does
not have a valid reverse lookup, indicating you are probably some type of
spam bot/virus that infected a machine. I can tell you this from
personal experience. If you would like I can dig up my mail server logs
from a while ago and show you.

If you will monitor your SMTP sessions, you'll see something like the
following:
EHLO jim.my.house //this is one of my machine's names

What happens now though is that I connect to, say, my work's mail server,
which is smtp.snip.net. I connect and they see my IP is 68.44.142.141.
My server says EHLO mail.my.house (or whatever your machine's name is),
and the reverse lookup says pcp05102306pcs.audubn01.nj.comcast.net. So
the domains don't match, and the mail is rejected. Now, what if I just
change my internal domain to comcast.net (ignoring other problems this
causes).

Most servers will now look up the MX record for whatever the IP address
was:
Address: 209.204.64.2

*** ns1.snip.net can't find 68.44.142.141: Non-existent domain

so now the receiving SMTP server sees that my IP is external, that the
reverse lookup isn't accurate, and I do not have a mail exchange record.
It'd be pretty weird for me to be running a legit mail server and not
have those things. Thus your email is rejected.

What you can do is as I said, relay through your ISP's server. They
should allow this, as it looks basically like a regular SMTP session and
you are on their network.

The reason I'm asking is because I want to be able to bounce e-mail, and for
some reason my ISP wont let me bounce from their mail server, so I figured I
could have a program that will change my computer into a mail server and
tell MailWasher to use that SMTP server.

I've downloaded a few programs. But none of them work, they just wont send
the e-mail.

It is not good practice to bounce mail.
With all of the spammers using other peoples addresses to spam with, when you
bounce email it gets delivered to a real person, but not a person involved in
spam.

It is better to drop the email.
