- If you send e-mail to sendmail.org, the answer will most likely not come from a system in the sendmail.org domain. Some anti-spam techniques (e.g., challenge-response systems) or block hosts that are connected via DSL prevent us from responding.
- To help prevent replies from being blocked, please make sure you do not block the following IP address:
18.104.22.168 or make sure that your system accepts at least STARTTLS secured mail.
- If you use a challenge-response system, make sure that it does NOT send a challenge when we reply to your question or when you receive mail from the announce list. We will not reply to those messages.
- The mailservers for sendmail.org use the following DNSBLs:
- The mailserver for support.sendmail.org performs strict RFC checks, for example, it does not accept mail if the domain part has an MX record that points to an IP address (instead of hostname as required).
