A Solaris compatibility package?

[Sergei Pokrovsky <pok@none.nowhere.invalid>]

The Solaris "Mailer" program produces attachments and forwards which
are not compatible with my gnus (I have "Mailer 1.3.0" and Gnus
v.5.8.8).  I do not know which one deviates from the standards, but
practically I use gnus for both mail and news.  But still, I have to
work which colleagues who often send me attachments or forwarded mail
which I cannot easily read.  That is, I can do it, but I have to save
it somewhere and and perform the necessary conversions outside gnus).

Now I wonder, given considerable number of people who use gnus on
Solaris, is there a plugin package which would enable me to easily
open an Solaris Mailer attachment, or a forwarded message presently
shown like this:

(Presently the only option offered is
"Save MIME part to: ~/sun-deskset-message".)
