Pretty cut-and-dried, I think. Looks like ACS mail servers want
rika.iab.uaf.edu's IP address to resolve to a hostname, and it doesn't:

$ host 137.229.80.111
Host not found.

In fact, neither does the hostname:

$ host rika.iab.uaf.edu
Host not found.

In fact, even asking UAF's own name servers doesn't cough anything up:

$ host 137.229.80.111 ns.uaf.edu
Using domain server:
Name: ns.uaf.edu
Address: 137.229.18.15
Aliases:

Host not found.
$ host rika.iab.uaf.edu ns.uaf.edu
Using domain server:
Name: ns.uaf.edu
Address: 137.229.18.15
Aliases:

Host not found.

Looks like hitting up the UAF admins would be the next step.
