One work around is replacing the '@' character with 'at' or something similar. However we did not want to do that, as we wanted a clickable link.

I think a good solution to this problem would be an e-mail address that changes periodically, say from: [email protected] to [email protected]. where abc.com (for example) would be the domain of my startup, and company the name of a customer. This changing e-mail would only be valid for a limited time.

The idea is to provide a piece of code that changes the e-mail and handling redirections. What do you think?
