Hi Guys,

1) I'm running OS X Tiger.
2) I haven't configured sendmail - not even sendmail.cf
3) I can send OK to some emails (eg. gmail) but not my own POP-mail.

I get the error:
--------
552 sorry, your envelope sender domain must exist (#5.7.1) (in reply to
RCPT TO command)
--------

My shellscript that sends the mail looks like this:

/usr/sbin/sendmail -oi -t -odb<<EOF
`echo "To: $recip"`
`echo "From: Myname <myname@mydomain.net>"`
`echo "Reply-To: Myname <myname@mydomain.net>"`
`echo "Subject: $sub"`
`echo ""`
`echo "$body"`
EOF

What to do?

Thanks in advance.
