Deleting an automatic created account

[Nicolas Martin]

Hi,

I posted to a list (Sane-dev) with a new email address, and this had for effect to create automatically a new user (Nicolas-96) which grabbed my new email address, and that I cannot change or remove.

The messages I send now to the list are systematically set to pending and take very long time to be published to the list.

I would like to set this new email address to my normal account.

How can I do ?

Thanks

Nicolas
