E-Mail Address This field displays when you select the E-Mail type. Enter an e-mail address or
domain name (up to 63 ASCII characters).
You can enter an individual e-mail address like abc@def.com.
If you enter a domain name, the device searches the source e-mail address string
after the “@” symbol to see if it matches the domain name. For example, you
configure a entry with “def.com” as the domain name. E-mails sent from def.com e-
mail addresses such as “abc@def.com” match the entry. E-mails sent from
mail.def.com, such as abc@mail.def.com do not match the entry since
“mail.def.com” does not match “def.com”.
You can also use a wildcard (*). For example, if you configure *def.com, any e-mail
address that ends in def.com matches. So “mail.def.com” matches.
The wildcard can be anywhere in the text string and you can use more than one
wildcard. You cannot use two wildcards side by side, there must be other
characters between them.
The device can check up to the first 63 characters of an e-mail’s address. The
whitelist or blacklist check fails for addresses over 63 characters. However, a
whitelist or blacklist entry that uses some text followed by a wildcard only requires
the device to check the number of characters before the wildcard. So the check
would still work for addresses longer than 63 characters. For example, if you used
“abc*”, the device would only check up to the first three characters of the e-mail
address.
Header This field displays when you select the MIME Header type.
Type the header part of an MIME header (up to 63 ASCII characters).
In an MIME header, the header is the part that comes before the colon (:).
For example, if you want the whitelist or blacklist entry to check for the MIME
header “X-MSMail-Priority: Normal”, enter “X-MSMail-Priority” here as the MIME
header.
Value This field displays when you select the MIME Header type.
Type the value part of an MIME header (up to 63 ASCII characters).
In an MIME header, the part that comes after the colon is the value.
For example, if you want the whitelist or blacklist entry to check for the MIME
header “X-MSMail-Priority: Normal”, enter “Normal” here as the MIME value.
Subject This field displays when you select the Subject type. Enter up to 63 ASCII
characters of text to check for in the e-mail headers. Spaces are allowed.
You can use a wildcard (*). For example, if you configure “*good”, any e-mail
subject that ends in “good” matches. So “this is very good” and “this is not so good”
both match.
The wildcard can be anywhere in the text string and you can use more than one
wildcard. You cannot use two wildcards side by side, there must be other
characters between them.
The device can check up to the first 63 characters of an e-mail’s subject. The
whitelist or blacklist check fails for subjects over 63 characters. However, a
whitelist or blacklist entry that uses some text followed by a wildcard only requires
the device to check the number of characters before the wildcard. So the check
would still work for subjects longer than 63 characters. For example, if you used
“abc*”, the device would only check up to the first three characters of the e-mail
subject.
