Bug#267004: exim4: When using a smarthost router: no IP address found for host smtp

[Cedric Delfosse]

Package: exim4
Version: 4.34-4
Severity: normal

In my network, the smtp smarthost machine is called "smtp", and it it resolved:

# ping smtp
PING XIII.metz (192.168.0.1) 56(84) bytes of data.
64 bytes from XIII.metz (192.168.0.1): icmp_seq=1 ttl=255 time=0.246 ms

The default domain name is metz, so the machine can be called smtp.metz too:
# ping smtp.metz
PING XIII.metz (192.168.0.1) 56(84) bytes of data.
64 bytes from XIII.metz (192.168.0.1): icmp_seq=1 ttl=255 time=0.248 ms

If I use "smtp" as the name of the smarthost router, I get this error:

2004-08-19 18:11:37 1BxpVp-0001bP-J9 <= root@replic U=root P=local S=274
2004-08-19 18:11:37 1BxpVp-0001bP-J9 no IP address found for host smtp
2004-08-19 18:11:37 1BxpVp-0001bP-J9 == cedric@metz R=smarthost defer (-1): lookup of host "smtp" failed in smarthost router

I don't understand why, because the "ping smtp" command show the host "smtp"
can be resolved.

But if I use "smtp.metz" as the smarthost, it works fine, the lookup doesn't
failed:
