Last cyrus login date

[Blake Hudson]

Hello, I'm working to implement a system that will automatically disable
a user's account due to inactivity. Inactivity is defined as a user not
logging into their mailbox within an arbitrary amount of time(90, 120,
... , n days).

I can handle the scripting if there's a way I can determine the last
time a user logged into their mailbox via POP/IMAP. I've tried looking
at the .seen and other cyrus files with no luck. I've also tried a perl
fud client port and it reports the last login date for all mailboxes as
being 0 (all other returned values make sense)... I'm using a virtual
setup on cyrus 2.2.12. Any help or direction would be appreciated.

Thanks
