Nothing in the config.

84s average connect time? Whoa!
At out box:
smtpd
28211 connections
1332 hosts/domains
2 avg. connect time (seconds)
13:48:32 total connect time

Is your DNS slow?
Do you have a caching DNS?
Do you have multiple DNS servers in /etc/resolv.conf?

% dig @dns1 MX charite.de
% dig @dns1 MX charite.de
% dig @dns2 MX charite.de
% dig @dns2 MX charite.de
