 When a DNSBL service reports an IP address as "black-listed", any additional DNSBL services/servers are not queried.
+If you have used zen.spamhaus.org in the past, this will no longer work. You will need to apply for a Spamhaus Data Query Service account at https://www.spamhaus.com/data-access/free-data-query-service/ where you will receive a unique key that is used to query their DNS.

+==== Archiving ====
+The Synchronet Mail Server (v3.21+) can automatically archive messages received via SMTP as separate ''.eml'' files in sub-directories of ''[[dir:data]]/user/####/'' (where ''####'' is the recipient or relaying user number).
+To utilize the mail archive feature, the sysop must set the "Archive Requirements" mail server setting (e.g. in [[util:SCFG]]->Servers->Mail Server) to specify the [[:access:]] requirements of the user or users whose mail should be auto-archived.
+Notes:
+  * Messages are archived after being processed by any external mail processors which may have modified the message header or body
+  * SPAM-tagged messages received for local users are not archived
+  * Archived messages are stored in ''.eml'' files, plain text files conforming to the RFC-822 internet message standard format
+  * Messages received for relay by users meeting the archive requirements are be stored in their ''[[dir:data]]/user/####/smtp_relay'' directory (i.e. like an "inbox")
+  * Messages received for delivery to local users meeting the archive requirements are stored in their ''[[dir:data]]/user/####/smtp_in'' directory (i.e. like an "outbox")
+  * There's no limit to the number or size of messages that may be archived, so disk consumption could be a concern
