#1930 virtusertable loses alaises

[Anonymous]

This problem has been intermittant for about two years
through several upgrades of Webmin and Sendmail on a
Redhat 9 box but I can't seem to track it down. A client
will login to webmin and delete one of their users then
for some reason all aliases in /etc/mail/virtusertable
associated with their domain will get deleted. Any help
would be appreciated.
