[Mailman-Users] mailaddresses with bad characters (resent)

i have posted this message before, but got no replies. it is really a problem for me.

hi list

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

if the solution is obvious, please tell me (even a "READ THE FAQ AGAIN !!" might help) if it is embarrasing, please tell me so too. but please, give me some(!) answer
