How to secure SMTP service?
Hello there,
I am using James only as a SMTP server. I have disabled the other services
(POP3, etc.). James runs on my root server. I don´t have any mailserver user
accounts. I am only sending noreply emails (no spam, just for user
registration :) ).
I have managed to configure James to run as an SMTP server. Now I want to
secure the SMTP service. I have identified three parts in the config file
that seem to be relevant.
<smtpserver>
<authRequired>true</authRequired>
<authorizedAddresses>mydomain.com</authorizedAddresses>
</smtpserver>
<mailet match="RemoteAddrNotInNetwork=mydomain.com" class="ToProcessor">
<processor> relay-denied </processor>
<notice>550 - Requested action not taken: relaying denied</notice>
</mailet>
The problem is I am a mailserver beginner.
I wonder if this is the right configuration for maximum security. Or do I
have to alter these settings?
Are there any other relevant security settings for SMTP?
