GreyListing

pc-tony.com operates a greylisting facility for all incoming emails.

All incoming email is temporarily rejected, and the server that is sending the message is told to try again in X number of seconds. This is to stem the flow of junk messages.

This methodology is very effective in stopping the majority of junk hitting any inbox. Most spammers are far too busy to go back and retry all failed/rejected messages. However if you are sending your message through a mainstream mail server, you should not see any problems.

If you have been directed here it is most likely because your message was greylisted, and your server does not understand the come back in X seconds command the mail server at pc-tony.com gives it.
