Bug#828801: Legitimate mail can contain long lines

Package: exim4-config
Version: 4.87-3
Followup-For: Bug #828801


I have just hit this issue trying to submit a bug report using the
reportbug package (which in turn connects to my Exim SMTP server to send
the message).

The message has a text file attachment that contains very long lines
(output of `bt full`) and this is enough to trigger this ACL.

This is a bad rule IMHO.
