Exim4 is Debian's default mail transport agent ("mail server software").
You don't strictly need to run Exim4, but you most probably need /some/
form of MTA in order to satisfy package dependencies.
The problem you are experiencing probably occurs because at the time
Exim4 starts, you don't have a network connection. Exim4 then tries to
do some DNS lookups and waits for an answer (probably for 30 or 60
seconds).

You can either solve Exim's problem or install some other MTA. Other
MTAs include nullmailer, ssmtp and a bunch of others. I cannot comment
on either of them.
But all you probably need to do is to run 'dpkg-reconfigure exim4' and
answer the questions to the best of your knowledge. There should be a
questions about whether Exim should "minimize DNS queries". That's
exactly what you need.

I don't recommend this solution since a lot of software (explicitly or
implicitly) depends on your system's ability to send mail.
