How to - Blocking & Exclusions
How To block /exclude email addresses & domains
The basic rule: XWall compares the
addresses from RIGHT to LEFT. The following examples
will demonstrate how to use the correct syntax.
| .com
|
This
blocks any email from ANY .com domain. Something
you probably don't want to do. |
| mail.com |
This blocks any email from mail.com and also any
email from hotmail.com |
| @mail.com |
This
blocks any mail from mail.com but not hotmail.com |
| .mail.com |
This
blocks mail from sub domains such as xyz.mail.com
, john@xyz.mail.com However this is an address block
and not a host block so it will not block a forged
address like xyz@zyx.com sent by a mail.com server. |
| ox@xyz.com |
This will block ox@xy.com but it also can block
fox@xyz.com |
| "
ox@xyz.com" |
This will only block ox@xyz.com . Don't type the
quotes (') it's just used to indicate the space
in front of the ox. A space signals Xwall to stop
comparing. |

Blocking or excluding IP addresses
This sytax is valid in the IP adders fields for blocking
or excluding IP addresses, including relay configurations.
| 192.168.1.2 |
will
block the address 192.168.1.2 only |
| 192.168.1. |
Will block any address from 192.168.1.1 to 192.168.1.255 |
| 192.168. |
Will
block any address from 192.168.1.1 to 192.168.255.255 |
|
192.
|
Will block any address from 192.1.1.1 to 192.255.255.255

Please note the "." On the end of
the IP addresses used for IP ranges.
Using Text and Subject blocks
Text and subject blocks are strings. A string is not
a word. If you typed the word the quote (") is
only used to point out spaces and such. DO NOT TYPE
the QUOTES shown in the examples.
| "spam" |
Spam
with no spaces before and after the string
will apply to Spam, spam, spamer, nonespam,
despaming |
| "
spam" |
Spam
with a space before the string will apply
to spam, Spam, spamer will not apply to nonespam,
despaming |
| "
spam " |
Spam
with a space before and after the string
will apply to spam, Spam and will not apply to
spamer, nonespam, despaming |
| "viagra" |
will
apply to viagra since it's a unique name you may
not add spaces |
| "v?i?a?g?r?a" |
applies
to v_i_a_g_r_a, v*i*a*g*r*a, v=i=a=g=r=a, v_i*a=g+r&a,
Will not apply to v**iarga |
| "v*i*a*g*r*a |
