How to send e-mail w/out using port 25?

get a copy of MSN 5.

I don't think it'd work... I'm running linux.

Honestly, I wouldn't be surprised if it is a requirement that you use the MSN software to do this. It's probably intended to do so so that you can't use Linux to use MSN effectively. I think we all know how much Microsoft LOVES Linux. Not.

To solve your problem, though, why don't you just set up your own e-mail server on your Linux box? Use Postfix or some such and roll your own.

I was gonna post a few questions about just that issue.

1) What are you using for mail on the Linux box? Are you using a simple mail client that is trying to uses POP3 or IMAP to get/send mail from the MSN server?

2) Or, are you doing as rael9 suggested and trying to use an MTA (Mail Transfer Agent) like sendmail, postfix, or one of the others for a local mail system that is trying to use MSN as an upstream mail server?

EDIT: And it seems that MS wants users to access MSN through Outlook as an HTTP mail server. Check to see if there are any Linux utils that support HTTP mail, other than a webbrowser that is...

I think quite a few of the big named ISP's are blocking port 25 to prevent spammers. What they don't want is someone getting an account and then setting up a relay on their own and spamming thousands of emails.

So the only port 25 traffic they will allow is their own server names. So you *could* spam from their own server but they would probably catch it pretty quick but if you tried using your own private server or someone elses server, you would probably get timeout errors or something to that effect.

When I used to do tech support for some internt products, that was an issue that we ran into all the time: Someone would buy a domain from xyz hosting and then they couldn't send mail to their new domain mail account because they were on MSN or Earthlink or whatever. The port 25 was blocked because it wasn't MSN's server.

Ugg. That drove me nuts with my ISP, as I sooo despratly wanted to run sendmail on my sparcstation classic (besides, I don't think that it has the power to send more then one email in about 30 min, so spamming wouldn't be very practical ). Most ISP's are shaping up, and starting to block these well known ports (8080 isnt so popular, hince me running http on it ). Cable ISP's seem to be more aggreseve, since all of the users bandwith is shared, and if you were to get slashdotted, well, you know where all of that bandwith goes...

It might behove you to use some other MTA than sendmail anyway. sm is full of a bunch old standards that most people never use, andd usually misconfigure. Another, leaner, modern leaning MTA might run better on an old box loike that anyway.

Kick your Sendmail to da curb! http://www.postfix.org

Of course, the one thing it can't do is penetrate an ISP block of port 25. ;^>

One thing to consider with getting an ISP.. If you get a "business" account (probalby quite pricy) they most likely will not block port 25 since its an actual business account.

Now If only I could convince my parents to spend an extra $20 per month so I can use my linux box on the web... Well, I can dream, can't I...

Sorry about resurrecting a 2 month old post, but, hey, I can help. If you have your own domain (mine is $8/year at names4ever.com) you can set up an account at uucpssh.org. Follow their instructions for getting it running under Postfix. Once you have it working and you have their servers as MX in your domain's DNS records, add the following to your postfix/main.cf:

relayhost = uucpssh
default_transport = uucp

That will send all the mail sent to your local SMTP server to their server over SSH, and their server will send it out. Seems to work as it should for me, though some ISPs block mail sent through it as possible spam. It also lets you host email for your domain without running it off of your connection (err, that's what UUCPSSH is supposed to be for).

I currently have 2 domains using uucpssh with Postfix on OS X as the local server. I really need to get around to writing something on how to setup UUCPSSH with OS X, I'm sure there are a lot of people that could use it. If you have any problems, email me or go to #uucpssh on FreeNode.
