    Angry Default Postfix Configuration

    Unable to send email via command line. My provider rejects my emails because of invalid domain.

    Is is possible to setup SMTP on SUSE 11.1 so that I can bypass my provider to send mail ???

    HELP

    Yes. I am using sendmail instead of postfix, but the principles are the same. When you don't specify a "Smart" relay host all mail will be delivered directly to the recipient host.

    What command are you typing?

    If you are trying to send from an invented address, most sure any e-mail
    servers rejects to talk with you.

    Try sending "from" a real/existant address or be sure to "convert it" to a
    real one. Postfix can do that.

    I assume you are unaware of the relayhost setting. If so you should try this first, setting it to your ISP's outgoing server. It may still object to non-existent sender domains though.

    However, out of the box, openSUSE postfix will do its own delivery. If you are still encountering your ISP's SMTP server, then it is likely that they have instructed their routers to divert all outgoing port 25 connections to their own SMTP server. This is one way to catch subscribers who have been infected with spam sending viruses.

    If that is the case, then you cannot bypass your ISP's SMTP server and you have no choice but to make sure that any sender domains in your email are not bogus.
