Why does Roundcube remember deleted email accounts?

[Rob Swan]

Whenever you log into an email account using Roundcube, that email account is added to the Roundcube MySQL database, it then uses that to store any settings you have for that account.

The information is stored in the users table, within the database simply called roundcube.

So, if you wanted to clear the stored details, you could delete the entry for that user using phpMyAdmin.

This can also be done in PuTTY, using this command.
sudo mysql -u root -e "DELETE FROM roundcube.users where username='fred@mydomain.com';"

Don't forget to replace fred@mydomain.com, with your the actual email address, that you want to clear.
