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 , This e-mail address is being protected from spambots. You need JavaScript enabled to view it However this is am address block and not a host block so it will not block a forged address like This e-mail address is being protected from spambots. You need JavaScript enabled to view it sent by a mail.com server.
This e-mail address is being protected from spambots. You need JavaScript enabled to view it	This will block This e-mail address is being protected from spambots. You need JavaScript enabled to view it but it also can block This e-mail address is being protected from spambots. You need JavaScript enabled to view it
" This e-mail address is being protected from spambots. You need JavaScript enabled to view it "	This will only block This e-mail address is being protected from spambots. You need JavaScript enabled to view it . 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 not 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 use to point out spaces and such DO NOT TYPE the QUOTES shown in the examples.

"spam"	Spam with no spases before and atter 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 an 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	will apply to valium, ice-cream apple, grapes, record, auto... and anything else you can think of
