Long delay when sending mail

[Sasa Stupar]

Hi!

I have configured mail server on FreeBSD 5.4 with sendmail 8.13.5 and 
cyrus-imapd v2. I am also using client Mulberry (but also tested with 
Tbird, Outlook Express, Outlook). I use IMAP access with all the clients, 
the server is on the same network as clients (100 Mbit network). The issue 
is when I try to send several messages one after another I get smtp delay 
message and this sometimes takes for 30 sec to a minute. My sendmail has 
configured a smart host and also to accept unqualified domains.
I have attached my sendmail config.
What am I missing here?
