| Post subject: | SMTP relay |
I can't send email through my local ISP using my university address, and I can't send email through my university anymore because I don't have a university IP. The solution I'm looking for is an SMTP server that accepts mail from anywhere (with authentication) and allows users to use whatever From: address they want. I've spent the last hour looking for a way to do this, playing with Postfix, exim, courier, etc., but can't find it. Perhaps I'm just looking in the wrong place. |

You can do smtp Auth with all of those you mentioned. Courier has support built in for it. With Postfix you need to use sasl and for exim I have no idea. Adam |

In exim, to accept relaying, you set the hostlist relay_from_hosts = line in exim.conf If you want the address rewritten (sendmail calls this masquerading, I believe), check the /etc/email-addresses file. |

Don't feel bad that you spent an HOUR working on this without getting anywhere. It took me quite a while to just understand how an MTA works, and what is actually needed to setup a secure SMTP relay. I use Gentoo, so I went with Postfix/Cyrus-SASL because alot of the Gentoo docs use this combo. Here are some links to the docs that I used: Gentoo Virtual Mailhost Guide Gentoo Server Project Wiki (currently down, so can't find the exact link) Postfix SASL Authentication and TLS The first 2 links aren't too gentoo-centric, so if you're on another distro these would still be good references. The 3rd was written for Postfix 1.x, so it's a little dated... but still good stuff there too. Why don't you give these a look and let us know where you're getting stuck. |
