Target list can add account

The list of ProspectLists modules is everywhere.. However it can be done using a number of core hacks.

First thing is to consider upgrading to 5.5, which will solve your problem immediately without core hacks.

I'd upgrade to 5.5, but I have one concern, which maybe you can help me with as well.
On 5.2 we modified the base of Sugar login and system configuration setting, by adding IP address validation. It allows us to define whether given user should be able to login when he/she is coming from an IP matching the one we assigned to him/her. Basically, our version of sugar is deployed on the internet, but we want certain users to be able to access it from anywhere and others only if their IP is matching the one we have predefined. Perhaps, there is a better way of handling such trivial security (i dunno if you can even call it security) feature?

So, in 5.5 I'd be able to create a module in the studio and create the relationship there with prospects as opposed to implementing all this hacks as mentioned in this post?
Thanks

So I did an update to 5.5 on my test env and it doesn't seem like this working. How do you set up the relationship between custom module and target lists for this work?

As I understood it, you wanted to use Accounts in ProspectLists, not a custom module? I'm sorry if I put you on the wrong track, but in 5.5 it's still not possible to do this without core hacking. The code differences between 5.2 and 5.5 thought me the code changes needed to achieve this, they are numerous..

So, i went back to 5.2, fixed the relationship and now email count is correct. But, when I sent an newsletter with contacts from my custom module i get this error
Fatal error: Cannot access empty property in this file

  root/modules/EmailMan/EmailMan.php on line 331 
  

the error occurs in this function

 function create_ref_email 
  

Does this function have to be called? I can try to trace it back, but I want just simple mass email on my custom module to be sent without going through so many settings, hooks and troubles. Are there other modules that could be used to send simple mass emails or how can I simplify this module?
THe message is sent anyway, but that error is just annoying
