The mailing list for listmasters using Sympa

["antonelli@cnaf" <address@concealed>]

Dear Sympa,

I have a multi domain/robot Sympa 6.2.70 on CentOS 7.9.2009 and I'm 
facing this error:

I have two lists same-name@domain1 and same-name@domain2 and when I try 
to add the (yet) owner address@concealed of same-name@domain1 as owner of 
same-name@domain2 I get an error from database. I attach the output at 
the end.

Am I doing anything wrong (like configuration?) or how can I bypass this 
(provided that we authenticate only via an IdP/CAS and each user has one 
email)?

Thank you
cheers Stefano

This is the query showing the existence of address@concealed as owner of 
same-name@domain1

MariaDB [sympa]> select list_admin,user_admin,robot_admin,role_admin 
from admin_table where user_admin like '%address@concealed%';

| same-name              | address@concealed | domain1 | owner      |

and this is the error from wwsympa.log
