Possible workaround(s) for mail user temporary suspension?

[Christian Rößler]

Hallo everybody,

I was searching for a possibility to suspend an user account (mail 
account, primarily). After a little bit of internet research I just 
found a wish for exactly the same thing:

Can anyone tell me if this suggestion is already implemented in Kolab, 
and I am just too dense today to find it? And, if not, has anyone a good 
work-around for this?

Best regards,
