Understanding Users: E-Mail Addresses

Not-So-Web-Savvy-User: I'll mail you. What's your e-mail address?
Me: rakesh dot pai at gmail dot com
NSWSU: At? You mean "at the rate of", right?
Me: Yeah. Same thing.
NSWSU: rakesh dot pai? That's unusual, isn't it?
Me: Just send it to rakeshpai at gmail dot com, if that's too confusing.
NSWSU: No underscores, right?
Me: No. Just rakeshpai.
NSWSU: Ok. No capitals, right?

Anyone has had any similar problem distributing e-mail addresses?
