I don't think identd normally needs to run, but the identd port 113 should
be open on the server.  If the server is silently dropping port 113
packets, the remote host trying to pass mail will timeout before continuing
with the smtp connection.  My ISP idents me when forwarding mail, and I use
a firewall to reset the port connection.

Also make sure your dns is working properly.
