By default, the ProfileImportRules component sets the values of the default login and password properties for every new profile to the value of the email property. In the default schema for the dps_user table, login is varchar(40) and password is varchar(35). Therefore, importing e-mail addresses that are longer than 35 characters causes the import to fail.
If you expect to import e-mail addresses longer than 35 characters, you can change this behavior by editing the ProfileImportRules component so that it uses a different property as the default value for the login and password. Alternatively, change the database schema to increase the size of the login and password columns.
