can ispconfig account tables become corrupted?

[darthpaul]

I am new to ispconfig and have run into an issue with one email account. I cannot add aliases to the account be cause ispconfig believes the alias to be in use. ISPconfig also thinks the account name and email address are in use. Is there a table that keeps the account names and aliases that could have become corrupted?

All of our email accounts are last(5)first(2) so Dave Thomas would be thomada@wendys.com for example. Ispconfig does not show dave.thomas thomada or davethomas in use as accounts, email addresses, or aliases, but I cannot use any of them. When I try to create the account or add aliases ispconfig gives me an error that they are already in use.

Any thoughts?
