Anti-Spam Features<br />

• Reject on unauth pipelining — Rejects mail when SMTP commands are sent ahead of the<br />

message even though the SMTP server supports pipelining.<br />

Advanced Options<br />

Click the Advanced button to configure advanced client restrictions. These options are for<br />

advanced users only because they can have adverse affects on your mail delivery if not used<br />

carefully.<br />

• Reject on missing addresses — Reject mail when no recipients (To:) or sender (From:) were<br />

specified in the message headers. These fields are the optional To: and From: fields, not the<br />

corresponding Envelope fields.<br />

• Reject on missing reverse DNS — Reject mail from a host when the host IP address has no<br />

PTR (address to name) record in the DNS, or when the PTR record does not have a matching A<br />

(name to address) record.<br />

Caution: Many mail servers on the Internet do not have valid Reverse DNS records. Setting<br />

this option may result in rejecting mail from legitimate sources. Enabling this option is not<br />

recommended.<br />
