[Exim] long base64 line

Hello!

I use exim 3.35 and yesterday i got a mail with a base64 coded body that
had one 15kbyte Line as the last line.
Base64 lines should not be longer than 76 chars.
It let spamassassin 2.43 hang because of a very "expensiv" pattern
matching rule.
Why did exim accept this Mail?


regards,
Rene
