I guess some simple email address mangling trick would give you the same effect, e.g. base64 encoding:
print 'mm(' + base64.encodestring('mal@lemburg.com') + ')' mm(bWFsQGxlbWJ1cmcuY29t)
These kind of encodings could even be used in URLs and survive text->HTML->text conversion.
Here's some code and an example:
import base64, re
def encode_email_address(address, note=''): encoded = base64.encodestring(address + ' ' + note)[:-1] encoded = encoded.replace('=', '-') encoded = encoded.replace('+', '.') encoded = encoded.replace('/', '_') return 'mm(%s)' % encoded
def decode_email_address_part(mangled_address): mangled_address = mangled_address.replace('-', '=') mangled_address = mangled_address.replace('.', '+') mangled_address = mangled_address.replace('_', '/') decoded = base64.decodestring(mangled_address) return decoded.split()
