[Mailman-Users] Error Unsubscribing: Not subscribed

[Who Is Testing?]

Error Unsubscribing:

*	mail at domain.net -- Not subscribed

Help!

I seem to have a 'stuck' user. My list shows the above error whenever I 
make any changes to the mebership of the list I run. The email address 
in question shows on the Membership List as being subscribed. However no 
mail is sent to that address, and I can't remove it from the list in 
order to resubscribe it properly.

Any suggestions?


TIA
