firewall or not

[Torgeir Veimo]

I have a question about the safety of the pop3 daemon that comes with
qmail-ldap.

I really would like to have a mail machine outside our firewall. I will
juse enable qmail-smtpd from the outside, along with qmail-pop3d. SSH
will be open only from our own network.

I know qmail itself is very safe, but how safe is the pop3d daemon? Has
it been audit'ed by any security person?

Lastly, is there an easy way of configuring openldap to only listen on
127.0.0.1 and not on all interfaces?
