[Mailman-Users] mailaddresses with bad characters

[IOhannes zmoelnig]

hi list

running my mailman-list, i have come into following problem:
some user prefer extra-cool (aka stupid ??) email-addresses like
cool^man at coolplanet.com

i cannot subscribe these addresses (as administrator, i do not know, 
whether they can subscribe themselves -- but i am porting my lists to 
mailman so this is my task)

are there any possibilities to do so ??
or do i have to teach my users to avoid such names ?
