Calendar

[R. Hanscom]

Can anyone help me with a "calendar" question, or perhaps point me at the
right FM??  One user on my network is getting 3 mail messages from
calendar...one server is sending one, and the other server is sending 2,
about 7 or 8 seconds apart.  What determines if a machine sends out
calendar mail (other than the fact that the user has a file called
calendar with an entry for that day's date)??  How does calendar identify
users -- from passwd, or aliases, or what??  Will a user get mail from
every machine on the net that mounts his/her home directory, and runs
calendar??

Thanks.
