Yes, indeed. I didn't know that.
Here is some info if some people have the same problem.

dnslookup router called for correction@wallex
domain = wallex
DNS lookup of wallex (MX) gave NO_DATA
returning DNS_NODATA
DNS lookup of wallex (AAAA) gave NO_DATA
returning DNS_NODATA
DNS lookup of wallex (A) succeeded
157.164.136.240 in "0.0.0.0 : 127.0.0.0/8 : 192.168.0.0/16 :
172.16.0.0/12 : 10.
0.0.0/8 : 169.254.0.0/16"? no (end of list)
fully qualified name = wallex.wallonie.be
wallex.wallonie.be 157.164.136.240 mx=-1 sort=-52
domain changed to wallex.wallonie.be
rewriting header lines
re-routed to correction@???

If I try to resolve it via all nameservers:
grep ^nameserver /etc/resolv.conf | awk '{ print $2 }' | xargs -n 1 host
-t A wallex | grep wallex
Host wallex not found: 3(NXDOMAIN)
Host wallex not found: 3(NXDOMAIN)
Host wallex not found: 3(NXDOMAIN)

But ping wallex works
ping -c 1 wallex
PING wallex.wallonie.be (157.164.136.240): 56 data bytes
64 bytes from 157.164.136.240: icmp_seq=0 ttl=62 time=0.928 ms
--- wallex.wallonie.be ping statistics ---
1 packets transmitted, 1 packets received, 0.0% packet loss
round-trip min/avg/max/std-dev = 0.928/0.928/0.928/0.000 ms

There is no search or domain in /etc/resolv.conf and nothing in /etc/hosts

In fact the hostname is sufficient to do a search through the domain
name. If I do "hostname smtp68" (instead of smtp68.wallonie.be), and
then reissue a ping, wallex doesn't work anymore.

Thanks, I learned something new.
