Confixx + new Identities

[rapid10]

Hi,

i have installed the plugin Confixx authentication plugin. It works just fine.
BUT: If I create a new identity the e-mail address looks like [email protected].
The identity which was created first, is correct. Also the domain is wrong. It's always the same: domain.tld.

In the database there is in the column 'mail_host' always the same domain 'domain.tld'.

How I can fix this (problem)?

Many thanks to you!
