Email password rules

[tuberb]

I am migrating an existing host into my Plesk VPS. Many of the email accounts are set up with passwords that violate Plesk's rules; i.e. - either less than 5 characters, or the password is the same as the email name, or both.

I would prefer not to have to reconfigure all of the users' email client software to change their passwords. Is there a way to override or disable the rules for email passwords, so that I can set up the accounts to all have the passwords they have on the old server?

Thanks,

Barry
