LocalDomainFileRefresh
LocalDomainFileRefresh=(seconds)

[Version 2.1+] Setting this value will cause JSpamFilter to check the LocalDomainFile at the interval specified. If the timestamp of the file has changed, JSpamFilter will reload the domain list from the file.

• RCPT TO limiting (limits the number of recipients for any given message.)
• The FilterTest shows which keyphrases were hit in the tested messages.
• IP-based "greylisting", which allows relaying, but only when the "from" address is in the local domain list.
• Connections that successfully SMTP AUTH can also be treated as greylisted connections (the default is to whitelist anyone who successfully authenticates to the mail server.)

AllowRelay
AllowRelay=10.x 192.168.x 172.16.1.1

The IP address "whitelist." IP addresses in this list will explicitly be allowed to relay mail (overriding the LocalDomainList and the spam filter.) Additionally, a Received header will not be added to mail accepted from a whitelisted IP address (to protect internal network address schemes.) Blocks of addresses can be added using ".x" instead of a number. Separate multiple entries with spaces.

Block
Block=192.168.99.x

The IP address "blacklist." No mail will be accepted from the IP addresses (or blocks) listed. This overrides the "AllowRelay" parameter, and completely shuts out mail from the addresses (or blocks of addresses) listed. If not specified, the server behaves as if the list were empty. Separate multiple entries with spaces.

MaxRcptTo
MaxRcptTo=(number)

[Version 3.1+] Optional. Setting this value will cause JSpamFilter to drop connections if the specified number of recipients is exceeded.

AllowLocalDomainRelay
AllowLocalDomainRelay=(IP Address List)

[Version 3.1+] Optional. This IP Address "greylist" will only allow relay for messages using local domain names (the domain names in the LocalDomainList) in the From header. If the "From" header does not match a domain name in the list, the connection will be dropped.

SmtpAuthAllowsRelayFor
SmtpAuthAllowsRelayFor=(Local|All)

[Version 3.1+] Optional, default is All. Normally, mail clients that use SMTP Auth are treated as if they were on the "AllowRelay" whitelist; if you set this value to Local, then clients using SMTP Auth are treated as if they were on the "AllowLocalDomainRelay" greylist.

DebugIP
DebugIP=(ip.nu.mb.er)

[Version 2.1+] Setting this value will cause JSpamFilter to behave as if all inbound connections came from the specified address. This can be used (in a non-production environment!) to test for proper DNSBL operation.
