This is, IMO, a very special case.

Why do you think so? Normally, a mail server can be down
for up to a day, without any lost of mail.

I don't think iptables is more complex than postfix (in fact,
to some degree, it might even be more simple, considering
how complex postfix is). I do expect any administrator
handling postfix to also know iptables. Anyway, I don't think
this is a reason good enough to have postfix to not start
when you install it, and add one more step when configuring it.

You are also considering a specific case of the SMTP server,
where it is used to receive outbound emails. Sometimes, you
only install a mail server to handle system mails (like cron
jobs, and so on). In this case, it would really be not convenient
to have the daemon not starting by default.

Of course, YMMV depending on what you do with mail...
