Wait, wait. sorry, not opens, but opened.
[HostOS]# vzctl 101 start
[HostOS]# vzctl 101 enter
[VE101]# /etc/init.d/sendmail start
.... sendmail opens /var/spool/mail/* in this moment.
[VE101]# exit
[HostOS]# vzctl 101 save
[HostOS]# rm -rf /var/lib/vz/root/101/var/spool/mail
[HostOS]# vzctl 101 restore
