Hello chaps. Technical question.
I'm intending converting one of my old machines into a dedicated mail server, and then moving my mail from my ISP's server to the server in my house.
I'm assuming the following.
I have to pay extra for a static IP.
My ASDL dialer/router will then get that IP, and all other machines on the network (mail server included) can keep their 10.0.0.x addresses.
I then have to map the SMTP/POP request from the static IP via the port number to the IP of my mail box.
Is it that simple (yes, there's lots of security issues involved, but that's a seperate matter).
Have I missed something?

Sounds about right to me. You have your own domain name at the moment (which is used for SMTP mail)?
Should be just a case of getting your mail server on the internet, port address translating port 25 to the mail server and getting your MX records changed at your ISP. People usually use an ISP as a caching server too should your mail server ever be unreachable.
I didn't understand the POP part. Are you intending to use a POP3 connector to download your mail from the ISP or use POP3 to access your mail from the Internet?
Bit of both mate.
Obviously I want to access the mail from the machines on the privite side of the firewall. But I also want to be able to pull my mail off from anywhere else as well.
The machine is already an SMTP server, and that's dead easy. It's having it actually *get* the mail when someone sends me something (without going through the ISP mailservers - although using them as a cache seems a good idea) that I'm unsure on.
I *think* it's pretty straightforward.
Anyone actually running their own mailserver?

Getting the mail is easy. You just need to PAT the POP3/IMAP/WWW (depending on functionality of server) port through the firewall. You obviously need more than just an SMTP server as that's used for transporting mail rather than reading mail that has already been recieved. I've run my own mail servers previously (well other people's actually when we hosted them!).

At work, we're currently running Visnetic Mailserver - www.deerfield.com . Seem to remember it cost about £100.00 for a 6 user licence. Using Demon as an ISP, they cache any incoming mail if our server happens to goes down.
As a package it was dead easy to install and configure and needs very little looking after.
Even comes with a webmail feature that works pretty well.
The antispam filter has got better over the last couple of generations and now doesn't miss an awful lot.
You can also have an antivirus plugin (amongst others) that seem to get a good recommendation.

Just use a nix box, and Exim, or some such device.
You will need to forward any port 25 requests to this box, and also 110 if you plan to use pop3 externally.
Depending on your NAT and fireall, you might also have to forward some unpriv ports back thru to let the mails go back out. but this shouldnt really need to happen.
much easier with static ip no NAT tho

I'm running my own mailserver, mainly coz I'm a techie geek and tinker with computers more than a sane man should. Inbound mail goes to MessageLabs for anti-virus and anti-spam (coz I work for them) and their mailservers deliver the mail to my server on the end of my adsl line. static ip with port 25 PAT to a gentoo linux box running qmail as the mta. provides pop boxes by using courier-imap (which has pop3 built in).
Be carefull if you want to use your mail server from outside of your NAT'd LAN for sending mail. Does that make sense?
I mean imagine you are at work and use a web client or what ever client to send your mail to your home server which then forwards it to your ISP.
This is called mail forwarding and will get hacked by the script kiddies and spammers quicker than you'd believe.
There are a few ways to secure against this but it depends alot on what systems you are working with and what you are trying to achieve.
If you are just wanting to download mail from a remote location then there's not so much of an issue.
Get back to me if you need anymore info.

I wouldnt advise anyone to run a local mail server, its just too much pain,
your ISP is likely to kick you off if / once you get hacked / abused.
Your surfing WILL suffer, as billions of muppets attempt to relay thru you / hack you.
You will attract unwanted attention to you, and end up with a huge headache.
If you REALLY want your own mail server, just get a hosting package. from as little as a few quid a month, your away.

having run a 'nix box as my mail server for a while, I've now moved house and parted company with the mail server..
So now I'm looking for an easy solution, Windows based mail server with smtp/pop3.. I've already found the webserver app I'm going to use, that bit was nice and simple! any recommendations on free mail server apps?
BTW, it needs to be capable of dealing with multiple domains..
Cheers,
W

Yep. Me and several friends. None of us running Microsoft stuff, though. The description given so far is pretty much it. Although I'd add a firewall, just using NAT isn't enough. And you've got to be pretty sure your SMTP server is rock solid, since the scrotes will be pounding on it day and night.
