Mailscanner 4.05-3 build fails

[Timothy M. Lyons]

Hello.

I'm trying to install Mailscanner on a Sun Ultra5 running Auroralinux
0.42 (based on RedHat 7.3)

The build goes well until the very end when I get the following:

Preparing...                ###########################################

Installing tnef decoder

Preparing...                ###########################################
[100%]
package tnef-1.1.2-sizelimit1 is for a different architecture

Now to install MailScanner itself.

error: failed dependencies:
        tnef >= 1.1.1 is needed by mailscanner-4.05-3
Please do not forget to kill your MailScanner version 3 processes before
starting version 4.

Is there a version of tnef-1.1.2-sizelimit1 for linux on sparc64?
