Content type change corrupts PGP signature

[Boris Wesslowski]

Hi,

I recently switched from sendmail to exim and had to turn mutt's
allow_8bitmime off. Since then my PGP signed messages are corrupted.
The transport encoding modifies the content, e.g. the signature separator:

diff test1 test2
[...]
14c31
< Content-Length: 870
---
> Content-Length: 868
20c37
< Content-Transfer-Encoding: quoted-printable
---
> Content-Transfer-Encoding: 8bit            
24c41
< --=20
---
> -- 

Is there something mutt can do to avoid this?
