I installed Roundcube 1.6 on Ubuntu 20.4.
When I try to log in from Roundcube it fails to auth, in the mail log I am seeing user=info\@domain.com which should be user=info@domain.com
Why Roundcube is adding "\" before @ sign in the username? How can it fix it?
Any help will be appreciated.
Note: I also installed SquirrelMail, it successfully logins with user info@domain.com
