When you installed spamdyke, you specified the location of the configuration
file, spamdyke.conf
And I presume that you have looked at this file, and modified it to your
needs.

In this case, your user is being rejected because 95-64-115-3.netserv.ro
does not resolve to an IP address and you have put the following in
spamdyke.conf

reject-unresolvable-rdns

To whitelist someone who would be blocked by this rule, you could add the
following line to spamdyke.conf

rdns-whitelist-file=/path/to/whitelist_rdns

(where /path/to/ is the real path to the file - usually same place as
spamdyke.conf)

And you would create a whitelist_rdns file in the directory described above.


Now, in this file you can add:

95-64-115-3.netserv.ro

Which would allow ONLY connections with an RDNS of 95-64-115-3.netserv.ro to
bypass spamdyke's tests.

However, if you want to allow all of netserv.ro then you would add this
instead

.netserv.ro

Notice the dot (.) at the start. This is like wildcarding in a way, and say
anything ending in .netserv.ro

But as Sebastian says, are you sure you want to do this? This looks like it
is a broadband or dial-up internet access account, and should not be
attempting to send email to your mailserver.

If it is one of your users who you allow to relay through your mailserver
then again something is wrong, because when they authenticate with a
username and password when sending email, spamdyke should allow them to do
so without filtering them.

The alternative method is to enable the submission port (587) and only allow
relaying of authenticated users on that port, with no spamdyke blocking on
that port at all.

I'm sorry if this is not what you are asking and if I've misunderstood your
question.
