Hi
I checked the lines around these positions, found an email address which has just the name, the whole @.... part is missing!
These users are synched from an openldap server. Seems there are some failsafves missing on the ldap server side to avoid entering invalid emails.
Thanks for pointing out that the numbers in the error message indicate the lines numbers.
The faulty line is on line number +2 when visualizing the file.
