Well, Few days back, I got the invitation to Join Gmail For Domains and I was able to create an email address mayank (at) mayankgupta.com I know, I know I had this email address before but the negative was that I didnt had 2 GB of space and cool gmail design :) but now I have that and the only thing I had to change was the MX RECORD. I've also written the reviews of Gmail for Domains on my other blog which is famous for Software Reviews. I am already enjoying this service, however Now I am pretty much stick with mayankgupta.com (at) gmail.com as I used it extensively in last 2 years but I am going to keep on using this new avatar of my old email address :p
