RT4.0.6 Unknown encoding in received emails

It’s better as the emails are not hanging in the mail box, but it
still not the perfect solution as the content needs more time to be
read.
What is missing ?

“we8iso8859p1” appears to be an Oracle-only way of saying “iso-8859-1”.
I suspect that telling RT that those are equivalent is all that is
necessary. You can do that by adding the following to your
RT_SiteConfig.pm:

require Encode::Alias;
Encode::Alias::define_alias("we8iso8859p1" => "iso-8859-1");

You may also want to look into the software that is generating the mail
in question, and see if it can be altered to provide the standard name
for the character set.
