libgnutls30 upgraded to 3.5.5-3:

> ii  libgnutls30:amd64                    3.5.5-3                         
amd64        GNU TLS library - main runtime library

The patch doesn't do the trick.

Same error messages.

Client side (exim 4.84.2-2+deb8u1):
>   SMTP<< 220 TLS go ahead
> LOG: MAIN
>  TLS error on connection to ... [...] (gnutls_handshake): An unexpected TLS 
handshake packet was received.

Server side (4.87-3+b1):
> Okt 25 06:40:07 ... exim[14817]: 2016-10-25 06:40:07 TLS error on connection 
from (...) [...] (gnutls_handshake): Error in the pull function.

After downgrading again to 3.5.4-2 all mails got transmitted.
