GUI-based mailtool and "toolplaces" info wanted

[W. W. Looi]

Having come from Sun environment, I'm rather disapponted with RS6000's
environment. I've been trying to get xmh to work but to no avail. May
someone suggest other GUI-based mailtool(s) for AIX?

I recall reading somewhere a "toolplaces" tool called xplace that's part
of X11 distribution. Surprisingly, it is neither in /usr/bin/X11 nor
/usr/lpp/X11/Xamples/clients?!

Please help...

Thanks.
