Trouble with base64

[Gerhard Faehrmann]

Hi there,

for some reason, my MailScanner installation does not seem to decode base64
encoded messages. Or, at least it appears this way. When using a different
encoding, it will catch the virus, when using base64 it will not. I've tried
different versions of the MIME tools (currently using version
MIME-tools-5.411) and the base64 package (currently using
MIME-Base64-2.12-6) on a Linux Redhat 7.2 system. Any hints?

Thanks,

Gerhard
