Sorry, short answer cause not on computer:
Look at your IP address in log, then look at ruleset, you should find the problem easily

Hello,
My OpenSMTPD is having problems sending out emails. It gets a error message saying somthing like "received invalid command: "RCPT TO:<[email protected]>".
Turned on debugging but still no clue.
Anyone has any pointers? thanks!
Here is related log:
root@cactus:/usr/local/etc# tail -f /var/log/mail.log

And here is my smtpd.conf:
pki cactus.keda.io certificate "/etc/ssl/private/cactus.keda.io.crt"
pki cactus.keda.io key "/etc/ssl/private/cactus.keda.io.key"
listen on localhost
listen on eth0 tls pki cactus.keda.io auth-optional
table aliases file:/usr/local/etc/mail/aliases
table secrets file:/usr/local/etc/mail/secrets
accept for local alias <aliases> deliver to maildir "/var/mail/%{user.username}/"
accept from any for domain keda.io alias <aliases> deliver to maildir "/var/mail/%{user.username}/"
accept for any relay
OS is Ubuntu 15.04 and OpenSMTPD is compiled from 5.7.1 portable release.
Thanks,
Alan
