/usr/ucb/mail Question?

[kbesrl at ux1.cso.uiuc.edu]

I have a problem with /usr/ucb/mail.  When I save a message in a folder,
it never gets deleted from the original folder.  I guess there is a flag
that can be set to avoid this problem, but it is not documented in the
man pages.  Another problem is that when I delete a message, the next
return skips a message.  I am wondering where I can get an on-line
documentation for /usr/ucb/mail.

Thanks.
