[BlueOnyx:05074] Re: question on importing sendmail content fromnon-blueonyx server

[trasor]

I'm still working on this conversion process and now have a new issue.  
Some of the passwords for the accounts will not pass the password 
check.  The passwords are too short or are dictionary words, etc.  Is 
there a way to bypass the password checking process temporarily.
