Thanks everyone who responded. I finally found a web page which answered all my questions, and then some. The url is: http://www.spencerstirling.com/computergeek/email.html All I had to do was follow exim4's config prompts. I just had to specify my ISP's smtp mail server as the smarthost I wanted to use. Apparently my ISP does not require authentication on smtp to act as a smarthost. So that was also quite convenient. Since Exim4 uses encryption by default, I suppose I am okay in that respect too. I needed to make no changes in Exim4's config files. However, I did need to make the changes to fix the From and Reply-To address for each user (otherwise the sending domain would be localhost.localdomain)[]. But since I wanted only one user to use this email system (sending emails to various users externally), it was not much of a problem. I just put the right lines in .muttrc to fix it: # Set your From information set from=m...@some-email.com set use_from=yes set use_envelope_from=yes For mails sent out via scripts, I installed heirloom-mailx and used its -r flag to fix the from address, like so: $ echo mail body | mail -r m...@some-email.com -s mail config with exim4 toaddr...@some-email.com Regards. -- Please reply to this list only.

If I remember correctly when sending mail through my isp the from header was always rewritten to be from my isp email address. That's what I do (though using postfix). I also connect to the vps through an opnvpn tunnel. This means the configuration of the mail server there remains simple. I likewise forward the mail from my laptop through an openvpn tunnel to that server.

The idea is that email from that machine (and perhaps from lan machines) may be sent to any valid email address with reply-to address changed to a fixed email address. I'd suggest that you use exim and use your isp's mail server as a smarthost. When you install exim, the debconf questions will give you this choice. You'll need the hostname of your isp's smarthost. Local mail will be delivered locally, non-local mail will be sent to the smarthost (with address rewriting so that it appears to the receiver as coming from your public mail name (e.g. h...@example.com, rather than h...@myhome). If you want to receive public mail, you'd use something like fetchmail. Unless you're running a firewall, you'll already have port 25 (all ports) open. Installing an MTA will simply provide a server listening to port 25. However, with the standard debconf smarthost, I don't think it actually will be listening on your public IP, only on your localnet. I'd further suggest that you install the doc-linux-howto (something like that) package, probably in html format. You'll find lots of info, including mail admin howto.

I can give you a few suggestions, but email here won't be enough. Read EVERYTHING you can find about mail servers. Think 3 or 4 times about setting up your own mail server. The trouble is that if you don't do things right, you can end up as an open relay. If you have static IPs, you can end up having your server blacklisted. If you have dynamic IPs, you may be blacklisted because of having dynamic IPs, which may even happen for the same reason if you have static IPs. Many ISPs won't let you run your own servers. Most private citizens who set up servers, shouldn't. Of course, you're free to do what you want. -- Raquel http://www.byraquel.com As nightfall does not come all at once, neither does oppression.

If I remember correctly when sending mail through my isp the from header was always rewritten to be from my isp email address. If you have a static ip you may be able to send mail directly to mailservers around the internet, however if you have a dynamic ip, it will be blocked by most mailservers. Also your isp may block outbound port 25 traffic. Mine just redirects all outbound port 25 traffic to their mail servers. I get around this by having a vpn between my home network and my vps. I know you said you did not need to receive any incoming email, just be sure to keep port 25 into your network closed. -- James Richardson Debian GNU/Linux Consultant http://www.linkedin.com/in/jamesrichardsonconsulting ja...@jamesr.biz signature.asc Description: Digital signature
