My interpretation was mail: [e-mail]

[randunel]

My interpretation would be [e-mail], given that it's become the de facto standard, and [e-mail] looks like his main one.

I'm not sure it can be a de facto standard with the number of sites that flatly refuse to recognize + as a valid character in email addresses. There's so many that I gave up and started just using . instead.
