Hello, I have set up a postfix-dovecot server with smtp-auth using sasl by following this link: https://help.ubuntu.com/10.04/serverguide/C/postfix.html
It seems to be working OK. The only thing is that when I view my logs, I see a lot of 'relaying denied', 'noqueue reject', 'too many errors after rcpt', and 'disconnect' messages from a lot of unknown domain names and ip addresses. I'm hoping that this means that the server is secure and doing its job bouncing mail from unauthorized requests. *** Is that true? Even if it was true, it has to be slowing down the server receiving so many unauthorized requests. *** Is there a way to avoid this or is this just a function of life in the world of email spam? Would a spam filter like Spamassasin help this type of issue?
