iRule with two data groups both using external files one working (addr) and one not (str)

Hi Dave,

a datagroup entry is always a

key_name=key_value

(where the value can be empty) combination and the search is always performed on the "key_names". The

[class match -value]

or simply

[class lookup]

syntax will then TCL return the

key_value

instead of the boolean

of the native

[class match]

syntax.

I guess your iRule isn't working correctly since you compare the reverse-dns-lookup results with the key_names

str1

str2

str3

, etc. This wouldn't work unless your reverse DNS query would resolve to those strings (which I dont believe). So ,my best bet would be, that you have to flip the order or the whitelist-smtp-names datagroup, so that the FQDNs would become the
