looks like there is a buffer overflow.
it looks like msgArray overwrites mailstream in the vm_state structure
when checking the number of messages in the mailbox for the MWI during
registration.

also

vmu->maxmsg is not checked int the imap code path.
but I assung I have to log a feature request to get that to work

Patch not supplied as you did not like my last one liner.
