sendmail aliases/Realtek 8111 problem (bin/139870)

[Warren Block]

sendmail was ignoring existing aliases on startup.  This is apparently 
due to a network interface not being ready in time in combination with a 
not-FQDN hostname.

With a hostname of "lightning" (no domain), re0 configured by DHCP, and 
verbose sendmail logging:

050 WARNING: interface re0 is UP with 0.0.0.0 address
050 WARNING: local host name (lightning) is not qualified; see cf/README: WHO AM I

A restart of sendmail after startup works normally because re0 has 
acquired an address by then.  Entering a FQDN as hostname 
(hostname="lightning.wonkity.com") in rc.conf works also.

I would say that this is really a problem with re0 and not with sendmail 
startup, but don't really know.

re0 does a DOWN/UP three times on startup.
