Bringing this back on the topic of SuSE Linux...
It should be pointed out that the Yast2 Installation and configuration of Postfix ENABLES RELAYING BY DEFAULT, and it offers NO ability to turn this off. You have to dig into the postfix settings and wade thru the postfix clear as mud documentation on their site.
Uh, I don't know how you managed to come to that conclusion. The default installation of Postfix is to listen to localhost only and allow only localhost to send mails. That is a bit different from what you describe. Anything else is something you define, whether it is through yast or by editing the config files.
You probably misunderstood something when you configured the system.
Quite possible, since I've only been using Linux for 10 years.
However, if you go back and try it on a new machine (not likely, I know) and check the box in yast that says you will accept remote connections, you will find you have an open relay.
That is just *not* true. Stop spreading FUD about something you don't understand. If you like Sendmail better, fine, by all means use it, but trying to dis-inform others about Postfix or another MTA is something we (tinw) expect out of Redmond,WA, not from a Linux user.
Since you don't need an MTA at all if you were planning to pop your mail, this seems to be totally wrong headed way to do it. And, as I pointed out, its not the way Yast installs sendmail which has relaying denied.
You need at least a sendmail drop-in if you want something to accept the mail from e.g. fetchmail. And again, if you've got an open relay after installing and configuring Postfix it's your own damn fault. Theo -- Theo v.
