RBL Check
Real Time Black List (RBL)
Check this box to block emails from the IP addresses listed in RBL sites. If emails are to be blocked,
the IP address or URL of an RBL server must be entered. If you check RBL, then you will be
provided with the list
Authentic List
. Here you can configure IP addresses for which the RBL check
can be bypassed.
RBL Server URL
Enter the IP address of the sites to be blocked. Then click
Save

SMTP SPAM Filtering
Authentic Sender
Enter any sender’s email ID that you wish to bypass the spam filtering process. Click
Add
after
each entry.
Recipient List
Enter any recipient's email ID that you wish to bypass the spam filtering process. Click
Add
after
each entry.
Authentic Networks
Enter any sender’s network name that you wish to bypass the spam filtering process.
Example:
If you want to add email IDs from the domain r
outerfinder.yourdomain.com
, then add it as:
@routefinder.yourdomain.com
Blocked Networks
Enter the name(s) of any network(s) from which email cannot be sent. If any user tries to send an
email from a blocked network, the email connection is rejected. Click
Add
. A network can be
deleted as desired.
Sender Black List
Enter a sender email addresses to be blocked. Then, if the sender’s email address matches any
entry in the list, the email will not be forwarded. If all emails from a domain are to be blocked, add
this @ symbol before the domain name:
If you want to block all email from the domain
routefinder. yourdomain.com
, then add it as
@routefinder.yourdomain.com
If you want to block all email from the domain
routefinder. yourdomain.com
, then add it as
@routefinder.yourdomain.com
Recipient Black List
Enter a recipient’s email address to be blocked. Then, if the recipient’s email address matches any
entry in the list, the email will not be forwarded.
If all email from a domain is to be blocked, add this @ symbol before the domain name:
If you want to block all email from the domain
routefinder. yourdomain.com
, then add it as
@routefinder.yourdomain.com
Check for NULL Sender
If checked, email with an empty sender address sent to more than one recipient will not be relayed.
Note:
If the email contains only one recipient ID, even if this option is checked, the email will be
relayed to the recipient, since it is legitimate to have NULL sender address in error.
Reverse DNS Test
If you check this option, the SMTP Proxy will try to resolve the domain name part of a sender’s
email ID. If it is resolved to an IP address, then the email will be relayed. If the sender’s name is in
the Authentic List, then the reverse DNS test will not be performed for the domain.
Bad Patterns in Sender/Recipient Address
Enter any pattern in an email address that you would like to block. Then both the sender and
recipient email addresses will be checked for these patterns. If the patterns match, the email will not
be relayed.
Control Characters:
1.
Exclamation mark (!): Bypass the SPAM check for this entry alone.
Example: All email from or to the domain
abc.com
will be stopped except for
