I have Win98SE and my O2K I use primarily for extremely heavy traffic
of another email account.  O2K was unreliable in handling more than
that acct and mixing up accts that I stopped receiving more than one
account.

Looking for alternatives and OE is okay except for one big thing.  Its
primary purpose will be to handle messages to and from my employment
agencies which now total 20.

I send a "mass broadcast" email re my availability/unavailability and
find it best to send an email to myself b.c.c.'ing everyone on my
list.  But OE doesn't show who I sent the email to.  This makes it, in
one fell swoop, completely inadequate for this job unless I find how
to turn that on.

How do I do that, pls?  O2K does this automatically, but hoping
there's a way to turn this one, as it were, in OE.
