Hello,
I hope someone can help me here. I have a small wordpress website from
which I am sending emails using a free plugin to my ISP SMTP server over
STARTTLS (smtpauth.exchange.iinet.net.au:587.
Now I am trying OpenSMTP which should do the job but for some reason it
returns "550 Invalid recipient" when I try to send emails through it.
All I want is the MTA to accept the mail and forward it to the
smarthost. Any idea?
Here's my /etc/smtpd.conf file:
----------------------------------------
table secrets file:/etc/mail/secrets
listen on 192.168.1.101 port 25
action "relay" relay host smtp+tls://smtpauth.exchange.iinet.net.au:587
<http://smtpauth.exchange.iinet.net.au:587> auth <secrets>
match for any action "relay"
Try
match from any for any action "relay"
If that doesn't fix it, its because OpenSMTPD has build in protections
against accidental "open relay" configurations, requiring authentication
from a incoming non local connection. I'm guessing that 192.168.1.101
could make it non local, though.
If OpenSMTPD runs on the same machine as the webserver you could just
"listen on" your loopback device and let wordpress connect to
127.0.0.1:25. If it needs to be done over 192.168.1.101 it gets
complicated. You will need to activate authentication, which requires an
encrypted connection thus a need for a certificate.
