Gurus
I have neither of these configured(Reverse DNS and SMART_HOST)...Infact the machine i am working on is a standalone server not in any domain.
Suppose that i configure both,will smtp-gmail start accepting my mails? If so what is the security that smtp-gmail server has against spammers.How exactly are the smtp servers protected against spammers if all it requires is a SMART_HOST and reverse DNS lookup.
Am asking this to understand the E-Mail setup. I read in howstuffworks.com and got a little understanding...But this thing perplexes me..
Thanks
HG
