... but you only looked for an A record in the DNS. Exim looks for MX
records, and it is usually this that causes problems like this. Here we
are: when I look for an MX record for leopard.ebonet.net I get
MX lookup yielded SERVFAIL
Since Exim cannot determine whether there is an MX record or not, it
cannot proceed. It MUST NOT assume that it can just go and use a
matching A record.
