As a data point, I've successfully used the following combos:

IMAP server            client
-----------            ------
Solstice (Solaris)     Communicator 4.x (Solaris, Win{NT,95})
                       Pine (NetBSD/i386/sparc, Solaris, Win95)

UW (Solaris)           Communicator 4.x (Solaris, Win{NT,95})
                       Pine (NetBSD/i386/sparc, Solaris, Win95)

UW (NetBSD-sparc)      Communicator 4.x (Solaris, Win{NT,95})
                       Pine (NetBSD/i386/sparc, Solaris, Win95)


I will be testing Communicator 4.03 on NetBSD/i386 this weekend.
