    Not sure if this is postfix related at all...

    Mail is sent from my localcomputer to postfix, then via smtpauth to
    my DSL providers SMTP server:
    relayhost = smtp.dslextreme.com

    Sent a e-mail to a comcast user and got a e-mail bounce:

    204.127.225.26 does not like recipient.
    Remote host said: 550 [PERMFAIL] comcast.net requires valid sender domain
    Giving up on 204.127.225.26.

    Is this on my end or comcast's end?

    (No other problems sending mail)
