It is a common fake TLD used by home gateways for their internal networks.

I collected a list of distinct client host names from my mail servers (MX
and message submission servers) which did not match the DNS. A lot of
these will be internal names. I counted the most popular TLDs. .lan is the
4th most popular fake TLD, after .local (mDNS), .home (BT Home Hubs) and
.localdomain (trad.).

 135 internal
 137 cn
 143 ch
 146 lan
 155 hu
 163 pt
 164 za
 169 localdomain
 178 tw

1707 info

2823 uk
3582 net

If I only look at my MXs the list is quite different:

 107 internal
 107 se
 124 id
 124 th
 134 cz
 137 cn
 143 ch
 155 hu
 158 localdomain

(It seems spammers have learned not to use home gateway fake TLDs...)

For message submission I see the following:

   4 root
   4 sg
   6 fr
   6 site
   8 box
   8 it
   9 localdomain
  11 net
