SMTP problem.

Hi debian security geeks.

I have a woody box running as a mail gateway with postfix (popbeforesmtp
and local relay for and pop3 (soon to be imap just need
outlook 2002 in the company as it supports multiple imap and pop3
accounts). My problem is that my log seem to be running full of strange
messages like these.

Jul 23 06:17:53 mail postfix/smtpd[5472]: connect from
Jul 23 06:17:56 mail postfix/smtpd[5472]: disconnect from
Jul 23 06:17:58 mail postfix/smtpd[5468]: connect from
Jul 23 06:17:59 mail postfix/smtpd[5468]: disconnect from

I dont realy see why this is there it seams to come there in about 2-3
sec. How do i track this down - i have a firewall in front of it and it is
also running iptables - so it should be pretty secure but this should not
be there should it ???.

Sorry if me english is not so good - hope you can read it.

Mvh./Yours sincerely
