[Mailman-Users] Not knowing what address is subscribed

[Allan Trick]

We're getting some people wanting to check their address in Mailman to see 
how we subscribed them (we seeded lists with extracts from our main 
database), and they don't know what address we used for them.

The only way I can think of is to have them type in one at a time and ask 
for a password to be mailed.  But Mailman is kind of stupid and says it's 
sending a password reminder to whatever address you type in, whether it's 
subscribed or not.

Is there any way for a person to confirm the address they're subscribed 
under?  Or for Mailman to tell them "That address is not subscribed" if 
they type in one that isn't?
