Mask an email address by removing most of the first portion and replacing it with "..."

For example. If you have a variable in your template context named email_address, and its value is "[email protected]"

{{ email_address|mask_email }}

will render as:

[email protected]

If the part preceding @domain.com is shorter than 5 characters, only the first letter will be used, followed by "...". So if we have "[email protected]"

{{ email_address|mask_email }}

will render as:

[email protected]

    name, domain = email.split('@')
    if len(name) > 5:
        # show the first 3 characters
        masked_name = name[:3]
    else:
        # just use the 1st character
        masked_name = name[0]
    return "%s...@%s" % (masked_name, domain)

register.filter('mask_email', mask_email)
