Check that the host running sendmail can do a reverse lookup on the IP number of the clients connecting to it. Simply putting IPs and hostnames of all your client boxes into /etc/hosts should fix the problem. Alternatively, that delay could be due to the ident protocol. Ident is trivially easy to spoof which makes it a pointless waste of time. Putting: define(`confTO_IDENT', `0')dnl in your .mc file will stop ident getting in your hair. The third possibility is that you've got quite a few milters set up there and sendmail simply needs a bit of time to run each message through all of them.
