  1. add Sender address rejected: Malformed DNS server reply 

    If we have some mailformed MX record like:
warning: malformed domain name in resource data of MX record for panzer.de
```
;; ANSWER SECTION:
panzer.de.		120	IN	MX	10 .
```
and someone put somewhere your host as MX so you will receive a lot of connections for it.
