The following are acceptable entries for URL Domain Black List:
If you enter the domain name in the format of www.domain.com, a URL must contain the entire entry (including www.) in order for the message to be identified as spam. Messages with only domain.com in the URL will not be identified as spam.
Example
Suppose you entered www.ipswitch.com into the URL Domain Black List. Messages with URLs containing exactly www.ipswitch.com, will be identified as spam.
Messages with URLs containing www.mail.ipswitch.com or other variations, will not be identified as spam.
If you enter a domain name in the format of domain.com, IMail Server looks for all URLs that contain domain.com, whether or not it is preceded by anything. For example, the URLs www.domain.com and www.mail.domain.com would both be identified as spam, because they both contain the entry domain.com.
Example
Suppose you enter ipswitch.com into the URL Domain Black List. Messages with URLs containing ipswitch.com, will be identified as spam..
AND
Messages containing URLs with other text surrounding the domain will be identified as spam.(i.e. www.ipswitch.com, and www.mail.ipswitch.com)
