I sent a message to someone, but they say my message never showed up, why?

We would like to point you to the following facts first:

• AZC mail servers run the best Internet mail system software qmail
• as pointed out in "What are the most common reasons for using qmail?" qmail by design won't lose email. If an address is deliverable, it will send the message. BUT, whether an address is always deliverable is not guaranteed. A lot sites on the Internet (especially Microsoft shops) have misconfigured or buggy mail server software, see e.g. the following official Microsoft bug repot:
  XFOR: SMTP Service Doesn't Retry on 4xx Errors

  qmail, on the other hand, has none of the mentioned bugs. In fact, since the version 1.03 released in November 1998, it has been so reliable that no fixes are necessary for regular operation and security issues so far. Quite a few companies that went IPO in the past and received billion dollar market caps use qmail as well. Examples: Critical Path, Yahoo!Mail, and even Microsoft's hotmail uses qmail for outgoing delivery. Please see qmail: Second Most popular MTA on the Internet for more details.

On the other hand, you can't trust end users's conjectures regarding the possible causes of the email difficulties, because of:

1. malfunctioning mail servers
2. accidental deletion of your message by the recipient
3. mistaken blocking or deletion by an account user's filtering service. In such cases, your messages may be delivered successfully, but your recipients will never see them, and most likely won't be aware of your messages's existance at all.

The best way to deduce the reason for "non delivery" is to double check

• when you sent the message
• who didn't get your message

While we can help you in receiving a message, once the message is sent, it is up to the recipients ISP to make sure the message arrives safely.
