SMTP and POP Idiocy

My mail server suffers a lot of fools anymore. It seems that all too many wish to send mail though they are unqualified to do so ...

First of all, if you don't have a current TLS/SSL certificate you are not going to adequately negotiate my encryption ... though I do support anonymous no cert deliveries for the time being.

Secondly, if you don't have an MX (mail exchange) record in DNS you need to go elsewhere because that is a fatal flaw in your configuration as far as I am concerned.
 

THEN there are the insipid inbred gadflies like internet-census.org and the faker exploitation sites like netsystemsresearch.com who attempt to gain access to and use your resources to appear that you are doing their bidding. I personally don't care if they all die.

The vast bulk of email I receive is handled with my regular expression filters and gets discarded. You may think you're sending something but the server is simply tossing it and not telling you anything.

To think that I actually thought I was going to be able to omit firewall rules from the mail server. You can't be totally open with the internet because of idiots who want to exploit your resources for their own ends.

So I spend a lot of time with custom scripting and control file maintenance which would be unnecessary if these incessant third world spammer morons would simply go away.

Fat chance, huh? Guess I'll just keep right on scripting and configuring stopgap measures.
