Hello everyone,

Just joined the list, very new to Radiant and RoR in general, coming  
from a PHP background. I’m starting to get a bit of experience with  
Radiant and using this experience to enter into the word or Ruby and  
RoR.

So I’ve been experimenting with the Mailer extension, done a fair bit of  
reading over the mailing list archive and got the extension up and  
running. So of course, now that I have it running, the first thing that  
occurs to me that I need is a little data validation.

Ive seen this post:

And this post:

Which are kind of eluding to what I’m wanting to know, but I’m wondering  
if anyone can point me in the direction of some examples or tips on how  
one might add server-side validation to the Mailer extension, I’m  
guessing this is probably pretty thing for your Ruby guru’s, but coming  
from PHP, I’m still a little in culture shock mode :P.

Kind of intertwined with the server-side validation question, I also  
wonder if anything has been said in relation to the Mailer extension and  
protecting against your email form being used as a spam relay. Is this a  
possible danger when using the extension? And if so, are there any  
examples of even just some basic checks that one can do to mitigate this  
risk?

Thanks for having me,
